Given
Area =540cm²
Length =36cm
Width =?
Area of rectangle =lxb
36xb=540
B=15cm (I took area as 540cm² otherwise we would get b >l) or take l in m)
Now perimeter of rectangle =2(l+b)
=2(36+15)
2x51=102cm
This is ur ans hope it will help you in case of any doubt comment below

Step-by-step explanation:
Area of a rectangle =l×b=540 sq cm
=36×b=540 sq cm
=b=540÷36=15 sq cm
Perimeter of a rectangle=2(l+b)
=2(36+15) sq cm
=87sq cm
Hence, the width of the rectangle is 15 sq cm and the perimeter is 87 sq cm.
