Step-by-step explanation:
W = (2L -57)
P = 2×(L+W)
198 = 2× (L + 2L -57)
198 = 2× (3L - 57)
3L-57 = 198/2
3L-57 = 99
3L = 99+57
3L = 156
L = 156/3 = 52
W = 2(52) -57 = 104-57 = 47
so, the length = 52 ft
and the width = 47 ft
Answer:
length = 52 ft
width = 47 ft
Step-by-step explanation:
Perimeter of a rectangle
P = 2(W + L)
where:
- P = perimeter
- W = width
- L = length
Given:
- P = 198 ft
- W = 2L - 57
Substitute the given values into the formula and solve for L:
⇒ 2(2L - 57 + L) = 198
⇒ 2L - 57 + L = 99
⇒ 3L - 57 = 99
⇒ 3L = 156
⇒ L = 52
Substitute the found value of L into the expression for W and solve for W:
⇒ W = 2L - 57
⇒ W = 2(52) - 57
⇒ W = 104 - 57
⇒ W = 47
Therefore,
- length = 52 ft
- width = 47 ft
