Problema Solution

you are painting the white lines around the perimeter of a tennis court. You measure and find out that the perimeter is 228 feet and the length is 42 feet longer then the width.

Answer provided by our tutors

We will use the general equation for the perimeter of a rectangle:

perimeter=2w+2l


where 'w' stands for width and 'l' stands for length. With the given information, we can write:


Perimeter=228

l=w+42


Plugging this in, we get:

228=2w+2(w+42)


Solving for 'w', we get:

w=36 feet


Therefore,

l=36+42=78 feet
