Question

6 The length of a rectangular field is 100 m. If its
rectangular field is 100 m. If its perimeter is 300 m, what
is its breadth?
​

Answer 1

Answer:

Length (l) = 100 m

Breadth = x

Perimeter of Rectangle = 2(l+b) = 300m

300 = 2(100 + x)

300/2 = 100 + x

150 - 100 = x

x = 50 m

Then,

Breadth = x = 50 m

Answer 2

Hi mate ,

Given:

length=100m

To Find :

Breadth=?

solution

perimeter = 2(length+breath)

of rectangle

300=2(100+b)

300/2=100+b

150=100+b

b=150-100

b=50

Therefore the breadth is 50 m

Hope it helps!!
