In 9. and 10., estimate, and, the use a formula to find the perimeter

9, A square 22 in long on each side

10, A rectangle 13 ft long and 38 ft wide

In 9, the perimeter is 88 ft and in 10, the perimeter is 102 ft

Step-by-step explanation:

In question 9. The perimeter of a square can be given as

4 × length = 4L

If the square is 22 ft long, perimeter will be

4 × 22 = 88 ft

In question 10, the perimeter of a rectangle is given as 2length + 2width

That is 2(l + w)

If l is 13 ft and w is 38 ft, the perimeter is

2(13 + 38) = 2(51)

p = 102 ft

the answer will be
