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

Answer:

$A=24ft^2$

Step-by-step explanation:

we can see that

shaded region is right angled triangle

so, we can use area of triangle formula

$A=\frac{1}{2}\times b\times h$

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

$A=\frac{1}{2}\times 12\times 4$

$A=24ft^2$
