Question

The length of a rectangle is thrice its breadth. if the perimeter is 60 incm find the dimensions of the rectangle​

Answer 1

Answer:

Let breadth of rectangle= x

Length of the rectangle= 3x

Perimeter= 60 cm

2(l+b) = 60

2(3x+x)=60

3x+x=60/2

4x=30

x=30/4

= 15/2

Length= 3×15/2= 45/2cm

Breadth= 15/2cm
