In this article, we will learn what area is, and understand how it is calculated for each shape, in the most practical and simple way there is.
Shall we start?
Area is the definition of the size of something. In mathematics, which is precisely what interests us now, it refers to the size of some figure.
In everyday life, you have surely heard about area in relation to the surface of an apartment, plot of land, etc.
In fact, when they ask what the surface area of your apartment is, they are asking about its size and, instead of answering with words like "big" or "small" we can calculate its area and express it with units of measure. In this way, we can compare different sizes.
Large areas such as apartments are usually measured in meters, therefore, the unit of measurement will be square meter.
On the other hand, smaller figures are generally measured in centimeters, that is, the unit of measurement for the area will be square centimeter.
Remember:

ABCD is a rectangle.
Given in cm:
AB = 7
BC = 5
Calculate the area of the rectangle.
AB = 10 cm
The height of the rectangle is 5 cm.
Calculate the area of the parallelogram.
To solve this problem, we'll apply the formula for the area of a parallelogram:
Let's proceed with the solution:
Step 1: The given base is 10 cm, and the height is 5 cm.
Step 2: The formula for the area of a parallelogram is .
Step 3: Substituting the provided values, we get:
Therefore, the area of the parallelogram is .
Answer:
50
AB = 12 cm
The height of the rectangle is 4 cm.
Calculate the area of the parallelogram.
To solve this problem, we'll proceed as follows:
Let's perform each step:
Step 1: From the problem, we know:
Step 2: Use the formula for the area of a parallelogram:
Step 3: Plugging in the values of the base and height:
Therefore, the area of the parallelogram is .
Since this is a multiple-choice problem, the correct answer is Choice 2.
Answer:
48
AB = 15 cm
The height of the rectangle is 6 cm.
Calculate the area of the parallelogram.
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The base is equal to the length , which is . The height corresponding to this base is .
Step 2: We'll use the formula for the area of a parallelogram:
.
Step 3: Plugging in our values, we have:
.
Therefore, the solution to the problem is , which matches choice
Answer:
90
AB = 17 cm
The height of the rectangle is 8 cm.
Calculate the area of the parallelogram.
To solve this problem, we will calculate the area of the parallelogram using the given base and height dimensions.
Calculating the product, we have:
.
Therefore, the area of the parallelogram is .
Answer:
136
AB = 25 cm
The height of the rectangle is 13 cm.
Calculate the area of the parallelogram.
To calculate the area of the parallelogram, we'll use the formula for the area, which is the product of the base and the height.
Therefore, the area of the parallelogram is .
This corresponds to choice 1: 325.
Answer:
325
