Question

The length of a rectangle is 10/3 cm more than its breadth. If its breadth is equal to the side of a square whose perimeter is 24 cm, then the area of rectangle in square cm will be

Answer 1

Step-by-step explanation:

The length of a rectangle is thrice its breadth. If the perimeter of the rectangle is 120 cm, what is the breadth of the rectangle?

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

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
