The length of the rectangular pizza is 80 cm and the width is 40 cm. The pizzas were cut into square-shaped pieces

The length of the rectangular pizza is 80 cm and the width is 40 cm. The pizzas were cut into square-shaped pieces, the lengths of which are 20 cm. How many pieces are there.

To solve this problem, recall the formula for the area of a rectangle. The area of a rectangle is equal to the product of its length and width. S = a * b, where a is the length and b is the width. Let’s calculate the area of the pizza, knowing. that its sides are 80 cm and 40 cm.
S = 80 * 40 = 3200 cm ^ 2.
The area of a square is equal to the square of its side. S = a ^ 2. Let’s calculate the area of one slice of pizza.
S = 20 * 20 = 400 cm ^ 2.
Let’s calculate how many pieces you get.
3200/400 = 8 pieces.
Answer: 8 pieces.
