Eddi Din [679]

Answer:

B) $\frac{15}{4}$

Step-by-step explanation:

Area of a rectangle formula:

A = bh

Given:

b = $2\frac{1}{2}$

h = $1\frac{1}{2}$

Mr. Robredo is building a fence around a rectangular region with 36 feet of fencing. The area of the rectangular region is 65 sq

Rufina [12.5K]

P = 2(L + W)
P = 36
36 = 2(L + W)
36/2 = L + W
18 = L + W....L = 18 - W

A = L * W
A = 65
L = 18 - W

65 = W(18 - W)
65 = 18W - W^2
W^2 - 18W + 65 = 0
(W - 13)(W - 5) = 0

W - 13 = 0 .....L = 18 - 13
W = 13 L = 5

W - 5 = 0 L = 18 - 5
W = 5 L = 13

Not exactly sure which (length or width)...but one is 13 ft and the other is 5 ft
