Problem 1

Find the length of the square, where the area of the square is 753424 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 753424 cm²

So, the length = √753424 = 868.

The length of each side = 868 cm

Explanation

The length of a square is 868 cm.

Because the area is 753424 cm², the length is √753424 = 868.

Problem 2

A contractor is planning to tile a square floor with a length of 868 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 868 feet

The cost to tile 1 square foot of floor = 5 dollars.

To find the total cost to tile, we find the area of the floor.

Area of the floor = area of the square = a²

Here a = 868

Therefore, the area of the floor = 868² = 868 × 868 = 753424.

The cost to tile the floor = 753424 × 5 = 3767120.

The total cost = 3767120 dollars

Explanation

To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 3767120 dollars.
