Question

The length of a rectangle is two times its breadth and its perimeter is 60 cm. Find it’s breadth.​

Answer 1

Answer:

length=2x

breadth=x

perimeter=60

2(2x+x)=60

x=10

breadth=10

Answer 2

Answer:

Step-by-step explanation:

Formula for finding perimeter is : 2 *  ( l + b)

so , let length be l and breadth be b .

so 2 * (2b +b ) =  60

2* 3b = 60

3b = 60/2 = 30

b  = 30 /3 = 10

breadth = 10 cm

length = 10*2 = 20 cm

therefore , 2 * (10+ 20)= 60 cm

2* 30 = 60 cm
