Find the length of one of the sides of the rectangle (1) and square (2).

1. Area = 45 m², one side is 5 m, find the other side.

2. Area = 9 m², find the side length.

Let's solve the problems step by step.

Rectangle Side Length Calculation :

We are given the area of a rectangle, which is 45 m², and one side of the rectangle is 5 m. We need to find the length of the other side.

To find the area of a rectangle, we use the formula:
Area = length × width

Here, one side (let's call it the width, w ) is 5 m. Therefore, the equation becomes:
45 = 5 × length

To find the length, divide both sides by 5:
length = 5 45 ​ = 9 m

So, the other side of the rectangle is 9 meters long.



Square Side Length Calculation :

We are given the area of a square, which is 9 m², and we need to find the side length of the square.

To find the area of a square, we use the formula:
Area = side × side = side 2

Setting the equation with the given area:
9 = side 2

To find the side length, take the square root of both sides:
side = 9 ​ = 3 m

Therefore, the side length of the square is 3 meters.

The length of the other side of the rectangle is 9 meters, while the side length of the square is 3 meters.
