Answer:

72 cm²

Explanation:

Data:

base = 3 cm

height = 6 cm

The area of a right triangle is computed as follows:

Area = base*height/2

Replacing with data:

Area = 3*6/2

Area = 9 cm²

The shape is made of 8 right triangles, then its area is 8*9 = 72 cm²

Answer:

72cm^2

Explanation:

In this question, we are asked to calculate the total area of a shape made of several triangles.

Now since the triangles are identical in all ramifications, we only need to calculate the area of one of the triangles and multiply it by their numbers to get the total area of the shape in question.

Mathematically, the area of a triangle can be calculated using the formula below;

A = 1/2 * b * h

Where A is the area , b is the base and h is the height. From the question, we were made to understand that the base is 3cm

With the height being 6cm. We plug these values in the equation

A = 1/2 * 6 * 3 = 9cm^2

Now since there are 8 of this, the total area will be 8 * 9 = 72 cm^2
