Question

The length of a rectangle is three times its width. if the perimeter of the rectangle is 128 Meters. Find the length and breadth of the rectangle.

Answer 1

Answer:

48m and 16 m

Step-by-step explanation:

Let the width of rectangle be x

Then the length is 3x

Perimeter of rectangle = 128m

Perimeter= 2(l+b)

=2×3x+x

=2×4x

=8x

•8x=128m

=>x= 128/8

=>x= 16

Lenth of rectangle is 48m

Width of rectangle is 16m

Answer 2

Step-by-step explanation:

Let breadth be x m

let length be 3x

So, 2(x+3x)=128

=>8x=128

=>x=128/8

=>x=16

therefore, Breadth=16 m

Length=48 m
