A length of a rectangle is twice its width. The perimeter of the rectangle is 126 feet.

Answer: length = 42ft width = 21ft
Explanation:
Find width:
L = 2W
P = 2(L + W) = 126
Thus
126 = 2(2W + W)
126 = 2(3W)
126 = 6W
126/6 = W
21 = W
Thus, width = 21ft
But L = 2W => L = 2(21) => L = 42ft
Therefore, length = 42ft and width = 21ft
Answer:
252
Step-by-step explanation:
Because you just multiply:
126 times 2 = 225
