Answer:

<h2>Yes. It's a right triangle.</h2>

Step-by-step explanation:

If a ≤ b < c are the length of the sides of a right triangle, then

a² + b² = c².

We have:

a =30 ft, b = 40 ft and c = 50 ft.

Check the equality:

L = 30² + 40² = 900 + 1600 = 2500

R = 50² = 2500

L = R

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
