Problem 1

Find the length of the square, where the area of the square is 430,336 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 430,336 cm²

So, the length = √430,336 = 656.

The length of each side = 656 cm

Explanation

The length of a square is 656 cm.

Because the area is 430,336 cm², the length is √430,336 = 656.

Problem 2

Sarah is planning to tile her square floor of length 656 feet. The cost to tile a foot is 2 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 656 feet

The cost to tile 1 square foot of floor = is 2 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 = 656

Therefore, the area of the floor = 656² = 656 × 656 = 430,336.

The cost to tile the floor = 430,336 × 2 = 860,672.

The total cost = 860,672 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 860,672 dollars.
