## How to Solve Rectangle Area Problems Series

The How to Solve Rectangle Area Problems Series is a series of posts on the basics of solving rectangle area problems. This post is a summary of the rectangle area series.

1.) Calculating Areas of Geometric Figures discusses the notion of area and the intuitive derivation of the formula $A = l \times w$ where $A$ is the area of a rectangle, $l$ is its length and $w$ its width.

2.) How to Solve Rectangle Area Problems Part 1 discusses the basic problems involving area of rectangles.

3.) How to Solve Rectangle Area Problems Part 2 discusses intermediate problems involving area of rectangles. This involves solving the area given the rectangle’s perimeter.

4.) Rectangle Area Problems Quiz is a self quiz to be able to determine your understanding regarding rectangle area.

I hope you enjoyed this series. More series to come in the future.

## How to Solve Rectangle Area Problems Part 2

We have already learned the concept of area of a rectangle and solved sample problems about it. In this post, we continue the rectangle area problems series. We discuss three more problems about rectangle area.

The fourth problem below involves area preservation, the fifth is calculating the area given its perimeter, and the sixth requiring the use of quadratic equations.

Let’s begin.

Problem 4

What is the area of the figure below?  » Read more

## How to Solve Rectangle Area Problems Part 1

The area of a rectangle including square are the simplest to calculate.  As we have discussed in the previous post, they can be calculated by multiplying their length and the width. That is if a rectangle has area $A$, length $l$ and width $w$, then,

$A = l \times w$ or simply $A = lw$.

In this post, we are going to solve various problem involving area of rectangles.

Problem 1

The length of a rectangle is 12 centimeters and its width is 5 centimeters. What is its area?

Solution

Using the representation above, $l = 12$ and $w = 5$. Calculating the area, we have

$A = 12(5) = 60$.

The area is 60 square centimeters.  » Read more

## Calculating Areas of Geometric Figures

Area of geometric figures are very common in Civil Service Exams and also other types of examinations. Area is basically the number of square units that can fit inside a closed region. In a closed region, if all the unit squares fit exactly, you can just count them and the number of squares is the area. For example, the areas of the figures below are 4, 10, 8 and 20 square units.

The figures blow are rectangles (yes, a square is a rectangle!). Counting the figures and observing the relationship between their side lengths and their areas, it is easy to see that the area is equal to the product of the length and the width (Why?). » Read more
