Question

Estimate the area and perimeter. Each square represents 9 yd^2.

Answer 1

for area count how many squares : 12 whole squares + 3 whole squares( that are made of 6 half squares)= altogether 15 square
15*9=90+45=135 yd²

to find perimeter you need to count sides
4+1+2+1+2+3+1/2+2+(1/2+1/2)+2+(1/2+1/2)+2+1/2+2+1=
=10+4+10+1= 25 yd

Answer 2

Area about 135 yd². Perimeter 2p= 69 yd

Explanation:

Area:

Since each tiny square has the area of 9yd²

Counting the area we have 12 whole squares: 12*9=108 yd²

Counting the area, we have 6 half squares.

A tiny square has the side of 3 yds

l²=9

l=3

A half square is a rectangle, with a width of 3 and height=1.5

And we have 6 rectangles 6(3*1.5) =27 yd²

Total Area=108+27=135 yd²

Since in some parts the bleach is not exact is a little more than 135 yd²

Perimeter

The Perimeter is the sum of all sides. Each side measures 3 yds, then each half 1.5

22 * 3yd = 66yd

2 * 1.5yd = 3yd

2p = 69 yd
