Question

Please help me been stuck forever

Answer 1

Answer: $60\ cm^2$

Step-by-step explanation:

In the given picture, it can be seen that the height of the shaded triangle = 10 cm

The base corresponding to the height = 12 cm

We know that the area of a triangle is given by :-

$\text{Area}=\frac{1}{2}\times \text{base}\times \text{height}$

Now, the area of the shaded triangle will be

$\text{Area}=\frac{1}{2}\times \text{10}\times \text{12}\\\\\Rightarrow\text{Area}=60\ cm^2$

Hence, the area of the shaded triangle =$60\ cm^2$

Answer 2

60cm^2 is the area of the triangle.

The formula for a triangle is A = 1/2bh. We know the base to be 12cm (you are allowed to rotate the triangle) and the height is 10cm. When we use that in the equation we get:
A = 1/2bh
A = 1/2(12)(10)
A = 60.
