Problem 1

Find the length of the square, where the area of the square is 603729 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 603729 cm²

So, the length = √603729 = 777.

The length of each side = 777 cm

Explanation

The length of a square is 777 cm.

Problem 2

Alex is planning to tile his square floor of length 777 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 777 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 = 777

Therefore, the area of the floor = 777² = 777 × 777 = 603729.

The cost to tile the floor = 603729 × 5 = 3018645.
The total cost = 3018645 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 3018645 dollars.
