Question

the lenth of rectangle is twice its breadth and its perimeter is 96m

Answer 1

Let the breadth be x ,
2(l+b) = 96
2(2x+x)=96
2×3x=96
6x=96
x=96/6
x=16
therefore breadth means x= 16
length= 2x=2×16=32

Answer 2

Hi,
let length be 2x and breath be x.

perimeter of rectangle=2(l+b)

96=2(2x+x)

96/2=3x

48=3x

x=16

length=2x=32m.

breadth=x=16m.
