Question

1) The longer side of a rectangle is 2 more than twice its shorter side. The area of the rectangle is 40 sq

unit.

a) Form an equation connecting the sides and area of the rectangle.

b ) Calculate the sides of the rectangle.

​

Answer 1

Answer:

this is going to be ez

let the shorter side be x

a) longer side = 2x + 2

b) let the longer side be y

y = 2x + 2

area of rectangle = l × b

40 = y × x

40 = 2x + 2 × x

38 = 2x × x

38/2 = x²

19 = x²

square root of 19 = x

x = 4.35
