Question

the width of a rectangle is two thirds it's length. if the perimeter is 180 metres, find the dimension of the rectangle​

Answer 1

let the length of the rectangle be x

so, width = 2/3 of x

=2/3*x

=2x/3

perimeter of the rectangle=2*[b+l]=perimeter

=2*[2x/3 + x] =180

Answer 2

Step-by-step explanation:

let length of rectangle be xm

breadth =2/3 x

ATQ

2(2/3x + x) = 180

2/3 x + x = 90

x(2/3 + 1) = 90

x(5/3)=90

x=90(3/5)

x=54

so length = 54

breadth =(2/3)54=16
