Question

if the length of a rectangle is 3 more that thrice its length and its area breadth if the area is 1260 find its lenght and breadth​

Answer 1

Step-by-step explanation:

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
