Question

The length of a rectangle is 9 cm more than its

width. If the area of the rectangle is 36 cm2,
what are the dimensions? Justify your answer.

Answer 1

= 4 = x²

x = Answer: Length= 11 , Brteadth = 2

Step-by-step explanation: Let the breadth of the rectangle be x

length = 9 + x

area = 36 cm²

A.T.Q

36cm² = 9x*x

36 = 9x²

36/9 = 4 = x²

x = root of 4

x= 2

Therefore , breadth of rectangle is 3cm and length is 12 cm

verification:

l*b = 12*3 = 36cm²
