Let's call L the width of the rectangle and W its width. The area of the rectangle is the product between the length and the width, and we are also told that the area is 300 square meters, so we can write

Moreover, we know that the length is 5 meters longer than the width:

We have a system of 2 equations in 2 unknown variables, L and W. If we substitute the second equation into the first one, we get


which has two solutions: W=-20 and W=15. We can discard the negative solution since it does not have physical meaning, and now we can substitute the value of W into the second equation to find L:

<span>Therefore, the rectangle has width 15 meters and length 20 meters.</span>

Complete Question
It takes 28minutes for 7 people to paint 7 walls. How many minutes does it take 14 people to paint 14 walls?
Answer:
28 minutes
Step-by-step explanation:
It takes 28minutes for 7 people to paint 7 walls.
Hence, the today number of minutes for 1 person to paint the wall =>
7 people = 28 minutes
1 person = 28 minutes × 7 people =
198 people minutes = 7 walls
1 wall = 198 /7
1 wall = 28 people minutes
How many minutes does it take 14 people to paint 14 walls?
From the above calculation,
1 wall = 28 people minutes
14 walls =
= 14 walls × 28 people minutes/14 People
= 28 minutes
Therefore, it would take 28 minutes for 14 people to paint 14 walls.
