Snow Shovel

Example Problem

Ziggy Snow Removal Service charges $0.50 per square foot to shovel driveways after large snow falls. Mrs. Nevens would like to have her driveway shoved by Ziggy. Based on the diagram of her driveway below, how much will it cost to have Ziggy’s service shovel it for her.


Mrs. Nevens Driveway

Solution to Problem

The driveway is in the shape of a rectangle. To solve this problem, we will need to determine the area of driveway and then multiple that by Ziggy’s price per square foot.

Step 1) Determine Area: A = L x W (According to the diagram the Length = 32 ft. and Width = 14 ft.)

A = 32 ft x 14 ft = 448 ft2

Step 2) Determine Price

The total cost will be the area (square footage) multiplied by the cost per square foot. Looking back at our solution, in step 1, the square footage is 448 ft2. Looking back at the original problem the cost is $3 per square foot. So the total cost will be = 448 x $0.50 = $224.

When Is It Important to Know How Calculate the Area of a Rectangle?

A rectangle is a four-sided figure with parallel equal sides. If you look around, you’ll see so many objects in the shape of a rectangle, the most basic being a table, a carpet, and a box which are everyday objects typically seen in offices and at homes. In fact, most items constructed by people take on this shape.

In geometry, an important calculation that you can do is find the area of the rectangle. But why is it important? What is the shape of the walls you are in? What is the shape of your computer screen? Are these things in a rectangle shape? Do you see any paint or carpet around you? If you do, then you need to know that the area of the rectangle was used for figuring out how much paint would be required for a particular area on the floor.

You must know how to calculate the area of a rectangle, and the best part is, it is very simple — just multiple lengths of the rectangle with the width.

Area = Length x width - Rectangles are important in all walks of life, and therefore, you need to be able to calculate the area of the rectangle.
