A = L x W
L = W + 3
so equation
A = W (W + 3)
70 = W (W + 3)
or
W (W + 3) = 70
answer
D. last one
W (W + 3) = 70
They are both found by adding all the sides
Answer:
the sum is 360 degrees, which means
360 = 124 + 124 + 2x + 2x
360 = 248 + 4x
-4x = 248 - 360
-4x = -112
x = 28
Check:
124 + 124 + 2(28) + 2(28) =
360
Your answer is x = 28
