1. 238

2. 50 ft

The realm of a parallelogram is bh the place b is the bottom, and h is the peak. Since line segments AB and CD are conveniently horizontal, I will use the size of line phase CD as the bottom (which is 14), and the space between line segments AB and CD as the peak (which is 17). So

14 * 17 = 238

So the world of the parallelogram is 238.

As for estimating the world of the polygon within the drawing, first, take a look at the general size and width. The determine covers an space 8 items vast and eight items tall aside from the corners. So the higher restrict on it is dimension is 64. Now take a look at the higher left hand nook. A bit over 3 sq. items is not coated. So the brand new higher restrict to your estimate is 64 3 = 61 items. Have a look at the higher proper nook. Seems like about 3.5 items arent coated there. So the brand new estimate turns into 61-3.5 = 57.5. Trying on the decrease left nook lets us subtract one other 4 items giving 57.5 4 = 53.5. Decrease proper nook reveals one other 4 items or so uncovered, so 53.5 4 = 49.5.

Now take a look at the obtainable selections of 25, 35, 50, and 65 to see whats closest. And that is clearly 50. So the reply is 50 ft.

The right possibility is possibility third, i.e.,25 cm sq.. Rationalization: From the given determine its simply observed that the shaded area incorporates two congruent parallelograms and 4 congruent triangles. Space of a parallelogram is the product of base and peak. The realm of a parallelogram is 12 cm sq.. Space of a triangle is half of the product of base and peak. The realm of a triangle is 0.25 cm sq.. Since there are 2 parallelograms and 4 triangles within the determine, due to this fact the overall space is, Due to this fact, the world of determine is 25 cm sq. and the third possibility is appropriate.

4. 20 in^2

5. 35 items^2

4. Trying on the diagram, you may see that the determine is protecting an space that is 8 squares by 4, so the higher restrict on its dimension is 32. However we have to subtract from that higher space, the areas left uncovered within the 4 corners of that space. The higher left hand nook has about 2 sq. uncovered. Higher proper hand nook has a bit over 2 uncovered. Decrease left has about 2 uncovered and at last, the decrease proper has about 2 uncovered. So there is a bit greater than 8 squares left uncovered. And 32 8 = 24, which remains to be a little bit of an over estimate of the coated space. Trying on the obtainable choices of 10, 15, 20, and 35, the selection that comes closest is 20. So the reply is 20 in^2

5.This one is far simpler. Trying on the determine, you may instantly see that there is a 8 by 4 area on the backside of the determine that fully covers these squares. And the 8 by 1 area on the very prime with the curving line seems to be to be protecting about half of the squares so that will be about 4. And eight x 4 4 = 32 4 = 36. Trying on the selections of 20, 25, 35, and 40, the closest possibility is 35 items^2.

25 units Step-by-step clarification: Rely every entire field as one cm and depend those that are not entire as half a cm and also you get 25 units

50 ft Step-by-step clarification: As you may see the polygon on the grid is just not an everyday polygon, so to calculate the world could be very sophisticated with out having the suitable instruments, what we are able to doo is to attract a squre that covers the entire peak however not the overall size, that means we are able to take a detailed estimate of the world, the closest sq. that may be fashioned could be a 69 sq., and the estimated space could be 54, that will be the maximun space, so the reply could be 50 squared toes.
