Question

6. The length of a rectangle is twice its breadth. If its perimeter is 48cm, find the dimensions of the rectangle
​

Answer 1

Answer:

let. length =l

breadth =b

acc. to ques

l=2b

perimeter = 48

2*(l+b)=48

2*3b=48

b=8cm

l=2b

l=2*8=16

Answer 2

Step-by-step explanation:

Let the breadth of the rectangle be x

Length = 2x

By the given prob,

2(l+b) = 48

2(2x+x) = 48

6x = 48

x = 48/6

x = 8

So, Length = 2*8 = 16cm and Breadth = 8cm
