1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side

Answer:
52 cm^2
Step-by-step explanation:
Solve by splitting the figures into 2 parts and finding their areas separately:
Rectangle:
8 × 5 = 40
Triangle:
1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12
Total: 40 + 12 = 52
