Question

The length of the rectangle is two times it's breath .Its perimeter is 60.a) perimeter in terms x is ............

Answer 1

Answer:

let the breadth be x.

therefore length=2x

perimeter=2(l+b)

60. = 2(2x+x)

60/2= 3x

30/3=x

x=10 units

length= 2×10

= 20 units

breadth=10 units

Answer 2

Answer: x =10

Step-by-step explanation: perimeter of rectangle=2(l+b)

60=2(2x+x)

60=4x+2x

60=6x

10=x
