Question

A rectangle is 4 meters longer than it is wide. Find the dimensions of the rectangle if its area is 165 sq-meters.

Answer 1

width = 11 and length = 15

Explanation:

→ Find algebraic length and width

width = x ∴ length = x + 4

→ Find area

x ( x + 4 ) = x² + 4x

→ Equate to area

x² + 4x = 165

→ Solve

x = 11

→ Find length and width

width = 11 and length = 15
