Question

the lenght of a rectangle is 4 times the breadth if the perimeter is 125m find the length and breadth of rectangle​

Answer 1

let us assume ,breadth = x

let us assume ,breadth = xlength = 4x

let us assume ,breadth = xlength = 4xperimeter of rectangle = 125m

perimeter of rectangle = 2(l+b)

125m = 2(4x+x)

125m = 2(5x)

125m = 10x

125m/10 = x

12.5m = x

:• breadth = x = 12.5m

:• length = 4x = 4(12.5) =50m

Answer 2

Answer:

b=12.5 , l=50

Explanation:

let l be 4b

perimeter = 2(l+b)

125=2(4b+b)

125=2(5b)

125=10b

b=12.5

l=4b=4*12.5

l=50
