Answer:
The total area of the shape is 90cm^2
Explanation:
Here we want to calculate the total area of the shape.
We have 10 different right triangles with each having an equal measure of 3 cm by 6 cm
The area of one of the right triangles can be calculated using the formula;
A = 1/2 * b * h
Where b is the length of the base which is 3cm and h is the length of the height which is 6cm
Plugging these values into the equation above, we have
A = 1/2 * 3 * 6 = 9cm^2
The total area of the shape is thus 9 * 10 = 90 cm^2
