Question

The length of a rectangle is 4 times the breadth .If the perimeter is 125m , find the length and breadth of the rectangle
​

Answer 1

Answer:

Step-by-step explanation:

given, l = 4b

perimeter  = 2(l+b)

125 = 2(l+b)

125=2 ( 4b+b)

125=10b

b = 12.5 m

l = 4b = 12.5 x 4 = 50m

Answer 2

Step-by-step explanation:

Let the breadth is x and length is 4x

Perimeter of rectangle = 2(l+b)

125=2(4x+x)

125=2(5x)

125=10x

125/10=x

x=12.5

Therefore breadth is 12.5

Length=4×12.5=50
