Question

The length of a rectangle is 4 time the breadth.if the perimeter is 125 m find the length and breadth of the rectangle

Answer 1

Answer:

let the breadth of rectangle =x

length =4x

perimeter =2(x+4x)=125

5x=125/2

x=12.5

breadth=12.5

length=12.5×4=50 m

Answer 2

Answer:

Breadth= b

length=4b

perimeter=125 m

p=2(4b+b)

125=2(5b)

125=10b

125/10=b

12.5=b

Breadth=12.5m

length=4x12.5

=50m

mark me as brainliest
