Question

3. A rectangle is 8cm longer than it is wide. If its width is x cm and its area is 84cm², form an equation in x and solve it. Hence find the dimensions of the rectangle.​

Answer 1

x = 6

Explanation:

let x = the width

let x + 8 = the length

Area = w times l

84 = 14 x 6

width = 6

length = 6+8

= 14
