Problem 2

Lisa wants to cover her square garden, which has a length of 881 meters, with grass. The cost to cover 1 square meter is 5 dollars. How much will it cost to cover the entire garden?

Okay, lets begin

The length of the garden = 881 meters

The cost to cover 1 square meter of garden = 5 dollars.

To find the total cost to cover, we find the area of the garden,

Area of the garden = area of the square = a²

Here a = 881

Therefore, the area of the garden = 881² = 881 × 881 = 776161.

The cost to cover the garden = 776161 × 5 = 3880805.

The total cost = 3880805 dollars

Explanation

To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per square meter. So, the total cost is 3880805 dollars.
