Question

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m,find the length and breadth of the rectangle. Om int)​

Answer 1

Let the width of rectangle=x

Then length of the rectangle = 3x

Perimeter of the rectangle = 96cm

2(l+b) = 96m

X+3x = 48

x = 12cm

Breadth of rectangle = 12cm

Length of rectangle = 3×12=36cm

Answer 2

Answer:

Let length of rectangle=lcm

breadth of rectangle= bcm

Given length is 3 times its breadth

i.e. l= 3×b

Perimeter of the rectangle= 120 cm

i.e.2×( l+ b)=120

2×(3×b+ b)=120

2×(4×b)=120

8×b=120

b= 15 cm
