Randal's dad is installing a new pool in their backyard. The pool is a square and has an
area of 121ft? Randal's dad will then build a 4 ft wide deck to surround the pool.
What is the outside perimeter of the deck?
Answer:
76 feet.
Step-by-step explanation:
The side of the pool = square root of 121 = 11 feet.
With the deck the length of 1 side will be 11 + 2 *4 = 19 feet.
There are 4 sides in the outside perimeter so the answer:
= 4 * 19 = 76 feet.

One side of a triangle is one-fourth the longest side. The third side is
8 feet less than the longest side. The perimeter is
118. Find all three sides.
The sides have lengths of______ ,___________ , and________ feet.
Answer:
Step-by-step explanation:
Let's call A the longest side. The others triangle sides are B and C.
We know that B = (1/4)*A and C = A - 8
The triangle's perimeter is: A + B + C = 118
Substituting the values of sides B and C, we have:
A + (1/4)A + (A-8) = 118
Adding common terms: (2 + 1/4)A = 118 + 8
(9/4)A = 126 then, A = 56 feet
B = (1/4)A = 14 ft
C = A - 8 = 48 feet
