Question

The perimeter of a rectangle is 504 dm. Its length is 36 dm more than twice
its breadth. Find the length and the breadth.​

Answer 1

Answer:

length=180dm

breath=72dm

Explanation:

Let the breath be x

length be 2x+36

Formula:

Area of rectangle=2(l+b)

Solution:

2(x+2x+36)=504

2(3x+36)=504

6x+72=504

6x=504-72

6x=432

x=432/6

x=72

Breath=72dm

Length=2(72)+36

=144+36

=180dm

Verification:

2(72+180)=504

2(252)=504

504dm=504dm

Since,LHS=RHS

Hence,

The given solution:

length=180dm

breath=72dm
