What is Area - Review
The area is space within a shape. Calculating area is done simply through a formula
Area = Length x Width
Formula: Area = L x W
When using a formula, substitute the variables with the information provided.
Area = Length x Width
Formula: Area = L x W
When using a formula, substitute the variables with the information provided.
Finding the area of a 2D shape is by multiplying two known numbers of the shapes.
Finding a Triangle's area
Finding the area of a Triangle is done quite similarly to the area of a rectangle or square, but plus an additional step.
In addition, the terms "Length" and "Width" are called "Base" and "Height"
So when you see B x H you can imagine L x W
Formula: Area = (Base x Height) ÷ 2
In addition, the terms "Length" and "Width" are called "Base" and "Height"
So when you see B x H you can imagine L x W
Formula: Area = (Base x Height) ÷ 2
Find the Area
Work through these triangles to practice and get used to this formula.
We will share our responses together afterwards
Area = (B x H) ÷ 2
We will share our responses together afterwards
Area = (B x H) ÷ 2
