Holly is trying to get the best deal for her money. The pizza shop is offering two pizzas for the same price. The round one is 12 inches in diameter and the square one measures 10.5 inches on a side. Which pizza should she buy?

Area = πr^2

Radius, r = diameter / 2 = 12/2 = 6 inches.

π = 3.14

Area = 3.14 * 6^2 = 3.14 * 36 = 113.04 inches square.

To know the size of the square pizza, we will apply the formula for a square
