Need detailed answer for this:

Find the perimeter of a rectangle whose length is 4 times its breadth and has area 10000sq cm

Answer 1

Answer:

Let l be 4x and b be x

L x b=10000

4x square =10000

X square =2500

X=50 cm

So, l =200cm

B=50 cm

Perimeter =2(200+50)

=2x250

=500cm

It is your right answer..........
