Question

Rachel wants to carpet the rectangular floor of his basement . The Basement has an area of 864 square feet . The width of the basement is 2/3 its length. What is the length of Rachel's basement.

Answer 1

This problem looks similar to the other math problem posted here. OwO

Anyway, first represent the unknowns.
Let x = length
since the width is 2/3 of the length,
Let (2/3)x = width

Recall that the area of rectangle is just width multiplied by the length,
A = w * l
Substituting,
864 = (2/3)x * x
864 = (2/3)x^2
864 * 3/2 = x^2
1296 = x^2
Get the square root of both sides,
x = 36 feet (length)

Note that you should only get the positive root since dimensions (length, width, etc.) cannot be negative.

Hope this helps~ `u`
