Arectangle of area 350 square feet is 14 times as wide as it is long find its length and width

Given:

Area of rectangle = 350 sq. ft

Find:

Length = ?

Width = ?

Solution:

The area of a rectangle is: L * W = 350 sq. ft

W = 14 L

Substitute into the area equation:

L * 14 L = 350 sq. ft

14 L^2 = 350 sq. ft

14 L^2 / 14 = 350 / 14

L^2 = 25

Sqrt (L^2) = sqrt (25)

L = 5

Then from above:

W = 14 * 5

W = 70 ft.

Therefore, the length of the rectangle is equal to 5 ft. and the width is equal to 70 ft.
