Answer:

181 inches

Explanation:

A rectangle has a length of 11 inches less than 8 times its width. If the area of the rectangle is 4344 square inches, find the length of the rectangle.

The formula for Area of a rectangle = Length × Width = L × W

A rectangle has a length of 11 inches less than 8 times its width.

L = 8W - 11

A = 4344

Hence,

4344 = (8W - 11)W

4344 = 8W² - 11W

Hence:.8W² - 11W - 4344

We factorise

(8W+181)(W−24)

W - 24 = 0

W = 24 inches

Solving for Length

L = 8W - 11

L = 8 × 24 - 11

L = 181 inches
