Question

16. The width of a rectangle is two-thirds its length. If the perimeter is 180 metres, ​

Answer 1

Answer:

Let length be x

and breadth be 2/3x

then,

2(x+2/3x)=180m

2×5x/3=180m

10x/3=180m

x=180×3=540/10=54

x=54m

2/3x=2/3×54

36m

Answer 2

Step-by-step explanation:

let the length be x

so, width became 2/3x

and perimeter of rectangle is 2(l+b)

=2(x+2/3x)=180

=2x+4/3x

=6x+4x/3=180

6x+4x=540

10x=540

x=54

so,length is 54m

and breadth is 54×2/3

=36m
