Line CD
Step-by-step explanation:
The answer for this question is d
hope it helps
Number one is A. Two is D and I think three is A ( I'm not entirely sure about the last one)
Use Pythagorean theorem
so, a^2 + b^2 = c^2
400-144 = b^2
find the square root of 256
= 16
P = 2(L + W)
P = 228
L = 2W + 6
228 = 2(2W + 6 + W)
228 = 2(3W + 6)
228 = 6W + 12
228 - 12 = 6W
216 = 6W
216/6 = W
36 = W <=== width is 36 ft
L = 2W + 6
L = 2(36) + 6
L = 72 + 6
L = 78 <=== length is 78 ft
