Answer 1

Answer:

Given that,

A rectangle has a perimeter of 100 meters.

The width is 9 meters.

To find the length of a rectangle.

we know that,

Perimeter of a rectangle is,

$=2(l+b)$

where l is the length and b is the breadth.

Substitute the values we get,

$100=2(l+9)$$l+9=50$$l=50-9$

we get,

$l=41$

Answer is: length of the rectangle is 41 m
