Breadth of the rectangle is 15 m.

Step-by-step explanation:

Given :-

Length of the rectangle is 20 m.

Perimeter of the rectangle is 70 m.

________________________

To Find :-

We have to find the breadth of the rectangle.

________________________

Solution :-

As, we have to find the breadth of the rectangle.

Perimeter of rectangle = 2(Length + Breadth)

Perimeter of the rectangle is given.

Length of the rectangle is also given.

Let the breadth of the rectangle be x m.

When, we put the value in the above given formula of the perimeter of the rectangle then we can get the value of x.

A.T.Q

70 = 2(20 + x) \\  \\ 70 = 40 + 2x \\  \\ 70 - 40 = 2x \\  \\ 30 = 2x \\  \\  \frac{30}{2}  = x \\  \\ 15 \: m = x

Hence, the Breadth of the rectangle is 15 m.

Verification :-

For verification again put the value of the length and bteadth and put that equal to the perimeter of the rectangle. If L.H.S got equal to thr R.H.S then our answer is correct.

A.T.Q

70 = 2(20 + 15) \\  \\ 70 = 2(35) \\  \\ 70 = 70

L.H.S = R.H.S

Hence Verified
