Question

HELP PLEASE!!!

Architect Frank Lloyd Wright included a pool shaped like a right triangle in his design of Taliesin West in Scottsdale, Arizona. The sides of the pool that represent the legs measure 41 ft and 40 ft. Calculate the perimeter of the pool. Round the answer to the nearest foot.

A. 136 ft
B. 138 ft
C. 140 ft
D. 144 ft

Answer 1

a^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
41^2 + 40^2 = c^2
1681 + 1600 = c^2
3281 = c^2...take sqrt of both sides, eliminating the ^2
sqrt 3281 = c
57.28 ...rounds to 57 = c

so the 3 sides of ur triangle are 57,41,and 40. The perimeter is all three sides added together. So the perimeter is : 57 + 40 + 41 = 138 ft <==
