Question

The length of a rectangle is two times it'd breath ,it's perimeter is 60cm,than the length is

Answer 1

Hi!

Let the breath be = x
Let the length be = 2x
Perimeter= 60cm
Value of x=?


Perimeter of rectangle= 2×(L+B)
60=2×(x+2x)
60= 2(3x)
60=6x
x=10 cm

Thus, the

Breath= 10cm
Length= 2*10=20cm


Hope it helps...!!!

Answer 2

Perimeter of the rectangle = 2(l*b)
b = l/2
60 = 2(l+(l)/2)
30 = 3l/2
l = 2*30/3
l = 20 cm

The length of the rectangle is 20 cm
