Assuming the pilcrow is supposed to represent pi:
100
Answer:
The length = 120 feet
Step-by-step explanation:
Givens
Let the length = x
Let the width = 3/4 x
Perimeter = 420 feet
Formula
Perimeter = 2*L + 2*w
Solution
2*x + 2(3/4) x = 420
2x + 1.5x = 420
3.5 x = 420
x = 120
For #1- step 1: Simplify using the inverse of addition or subtraction.
step 2: Simplify further by using the inverse of multiplication or division.
