Answer:
A=55
Step-by-step explanation:
6+x=32
2x+2y=32
2x+2(6+x)=32
4x=20
x=5
and then y=6+5=11
A=x*y11*5=55
Answer:
A = 55 cm²
Step-by-step explanation:
Here, L = W + 6 cm, and P = 2W + 2L = 2W + 2(W + 6 cm) = 32 cm
Then 2W + 2(W + 6 cm) = 32 cm becomes:
2W + 2W + 12 cm = 32 cm, or
4W = 20 cm.
Therefore, W = 20 cm / 4 = 5 cm
The area of this rectangle is A = L · W = (5 cm + 6 cm) · (5 cm), or
A = (11 cm)(5 cm), or A = 55 cm²
