Problem 1

A rectangular garden has a length of 313 meters and a width of 200 meters. Find its area.

Okay, lets begin

The area of a rectangle = length × width

Area = 313 m × 200 m = 62600 m²

Explanation

The area of the rectangular garden is 62600 m². This is calculated by multiplying the length by the width.

Problem 2

Maya wants to cover her square floor, which has a side length of 313 feet, with tiles. If each tile costs $5, how much will it cost to cover the entire floor?

Okay, lets begin

The length of the floor = 313 feet

Cost to cover 1 square foot = $5

To find the total cost, we find the area of the floor: Area of the floor = a²

Here, a = 313

Therefore, the area = 313² = 313 × 313 = 97969.

The cost to cover the floor = 97969 × 5 = 489845.

The total cost = $489845

Explanation

To find the cost to cover the floor, we multiply the area of the floor by the cost to cover per square foot. So, the total cost is $489845.

Problem 3

Find the area of a circle whose radius is 313 meters.

Okay, lets begin

The area of the circle = 307,995.46 m²

Explanation

The area of a circle = πr²

Here, r = 313

Therefore, the area of the circle = π × 313² ≈ 3.14 × 313 × 313 = 307995.46 m².

Problem 4

The area of the square is 97969 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 1252 cm

Explanation

The area of the square = a²

Here, the area is 97969 cm²

The length of the side is √97969 = 313

Perimeter of the square = 4a

Here, a = 313

Therefore, the perimeter = 4 × 313 = 1252 cm.
