Question

If the perimeter of a rectangle is 10 times the width of the rectangle, then the length of the rectangle is how many times the width ?

Answer 1

we know that perimeter of a rectangle is P= 2(l+b)

we have given perimeter is 10 times the width

2l+2b=10b

we need to solve for l to find length is how many times the breadth .

2l=8b

l=4b

from this length is 4 times the breadth.
