Question

Find the breadth of a rectangle whose perimeter is 880 m and length is 315

Answer 1

Perimeter of rectangle = 2(l+b)

880=2(315+b)

880/2=315+b

440=315+b

440-315=b

125=b

Therefore,breadth is 125m

Answer 2

Given :

Perimeter is 880 m and length is 315

To Find :

Find the breadth of a rectangle

Solution:

Length of rectangle is 315 m

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle = 2(315+b)

We are given that the perimeter is 880 m

So, 2(315+b) = 880

$315+b=\frac{880}{2}$

$b=\frac{880}{2}-315$

b=125 m

Hence The breadth of rectangle is 125 m
