Question

A rectangle has an area of 80cm² and a perimeter of 48cm.

Find the length and width of the rectangle.

Answer 1

20,4

Explanation:

20+20+4+4=48

20*4=80

Answer 2

20,4

Explanation:

Suppose that x, y are the the length and width

Area=x*y=80

Parameter=2(x+y)=48....x+y=24

Xy=80...x(24-x)=80...x=20,y=4
