Question

Which equation can be used to calculate the area of the shaded triangle in the figure below?

(5 points)

2(12 × 4) = 96 square feet

(12 × 4) = 24 square feet

2(12 + 4) = 32 square feet

(4 + 12) = 8 square feet

Answer 1

`A=24ft^2`

Explanation:

we can see that

shaded region is right angled triangle

so, we can use area of triangle formula

`A=(1)/(2)* b* h`

where

b is the base of triangle

h is the height of triangle

we have

`b=12`

`h=4`

now, we can plug this in formula

`A=(1)/(2)* 12* 4`

`A=24ft^2`
