Question

A perimeter of a rectangular park is 270m . If its length is 75m. What will be its breadth

Answer 1

perimeter of a rectangular park is:2(l+b)
270=2(75+b)
270=150+2b
270-150=2b
120=2b
b=120/2=60m

Answer 2

Perimeter of rectangular park = 270 m

Length of rectangular park = 75 m

We know, perimeter of rectangular field = 2( length + breadth )

= > 2( breadth + length ) = perimeter

= > 2( breadth + 75 m ) = 270 m

= > breadth + 75 m = 135 m

= > breadth = 135 m - 75 m

= > breadth = 60 m

$\boxed{ \boxed{ \underline{ \text{  Hence, breadth of the rectangular park is 60 m }}}}$
