Question

Can someone help me please. I have to show my work.

Answer 1

4. area= 230cm^2 perimeter= 66cm

5. width= 7m perimeter= 32m

Explanation:

4. a = w*l

23cm*10cm=230cm^2

p= add all sides

23cm+23cm+10cm+10cm=66cm

5. w= a/l

63m^2/9m=7m

p= add all sides

7m+7m+9m+9m=32m

Answer 2

Explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

A = width * lengh = 23 * 10 = 230

2. width = 7

P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32
