Question

Please help.
What is the area of a triangle?
Please explain answer as well

Answer 1

Area = 12 units²

Step-by-step explanation:

We have given the figure.

We have to find the area of triangle in the figure.

As we know that the area is given by

Area = 1/2 (base)*(height)

In the figure,each square represents one unit , the base is BC in the figure.

base = BC = 8 units

The height is the perpendicular distance form vertex A to BC we get,

Height = 3 units

Putting the value in equation we get,

Area = 1/2 (8)(3)

12 units² is the area of triangle.

Answer 2

Area of triangle = 12 units²

Step-by-step explanation:

Area of triangle is calculated using the following rule:

Area = 0.5 * base * height

Now, in the given figure each square represents one unit, therefore, we will get the lengths by counting squares

Base = BC = 8 units

Height is the perpendicular distance from vertex A to the base BC = 3 units

Substitute with these values in the above equation to get the area as follows:

Area = 0.5 * 8 * 3 = 12 units²

Hope this helps :)
