Question

Please help me been stuck forever

Answer 1

Answer:
`60\ cm^2`

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}=(1)/(2)* \text{base}* \text{height}`

Now, the area of the shaded triangle will be

`\text{Area}=(1)/(2)* \text{10}* \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.
