Answer 2

Given:

•The length of a rectangle is twice the breadth.

•The perimeter is 228 m.

To find:

•The dimensions of rectangle

Solution:

Let us assume that the breadth of the rectangle be x and length be 2x.

We know that,

P = 2(l + b)

Where,

P is Perimeter of rectangle

L is Length of rectangle

B is Breadth of rectangle

A.TQ,

» 2 (2x + x) = 228

» 2 (3x) = 228

» 6x = 228

» 6x/6 = 228/6

» x = 38

So, x = 38

2x = 2×38 = 76

Hence,

Breadth of the rectangle = 38m

Length of the rectangle = 76m
