Question

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

Answer 1

Answer:

Perimeter,p= 125 cm

Breadth,b= ?

Length,l= 4b

Now, p =2(l+b)

125 = 2*(4b+b)

125 = 2*(5b)

125 = 10b

b = 125/10

b = 12.5 cm

Now, l = 4b

l = (4*12.5)cm

l = 50 cm

Answer 2

Step-by-step explanation:

For this rectangle ,

breadth = x

length = 4x

perimeter = 2 × ( length + breadth )

125 = 2 ( 4x + x )

5x = 125/2

x = 25/2 = 12.5 m

So , breadth = 12.5 m

& length = 4(12.5) = 50 m
