Question

the perimeter of a rectangular garden is 400m and it's length is 125m what is the breath of the garden​

Answer 1

Length of Garden= 125m

Perimeter= 400m

2 (l+b) = 400m

2 (125+ b) =400m

250+2b =400m

2b= 400-250

2b= 150m

b= 150/2 = 75m

Verification

2( 125 +75)

= 2× 200

=400m

Hence, breadth= 75m

Answer 2

It's easy u need to remember only perimeter formula.
