Question

Perimeter of rectangle is 96cm, lt length is 3 time its width find it lenth and breadth

Answer 1

Answer:

let the width be x

and let length be 3x

according to question

perimeter of rectangle = 2(l+b)

96 = 2(3x+x)

96/2= 4x

48= 4x

48/4 = x

12 =x

so, width = x = 12 cm

length = 3x= 12*3 = 36cm

hope it would help you!!!!

Answer 2

Answer:

length =36 and breadth =12

Step-by-step explanation:

P=2(L+B) L=3B

P=2(B+3B)

96/2=B+3B

48=B+3B

48=4B

48/4=B

12=B=Breadth

3B=length

3x12=36=length
