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.
