The area of the rectangle is 80 cm2. One side of the rectangle is 5cm. What is the other side equal to?

From the condition it is known that the area of ​​the rectangle is 80 cm2, and one side is 5 cm. In order to find what the second side of the rectangle is equal to, recall and apply the formula for finding the area of ​​a rectangle.

So, we look for the area of ​​the rectangle by the formula:

S = a * b, where a and b are the length and width of the rectangle.

We know the area and length of one of the sides of the rectangle.

Let’s express the length of the second side from the formula:

b = S / a;

We just have to substitute the values ​​and make calculations:

b = 80/5 = 16 cm length of the second side of the rectangle.

Answer: 16 cm is the length of the second side of the rectangle.
