Answer 1

Answer:

A = 220.5 ft

Step-by-step explanation:

$2(Length) + 2(10.5) = 63 feet$

$2L + 21 = 63$

$63 - 21$

$2L = 42$

$42/2$

L = 21 feet

$A=l * w$

$21 x 10.5 = 220.5 ft^{2}$

Hope this helps

Answer 2

Answer:

area = 220.5 ft²

Step-by-step explanation:

2(Length) + 2(10.5) = 63 feet

2L + 21 = 63

subtract 21 from each side of the equation:

2L = 42

divide both sides by 2:

L = 21 feet

area = L x W = 21 x 10.5 = 220.5 ft²
