Question

Can someone explain how to get the answer?

Answer 1

A = ((6 + 7 + 6) . 8)/2
A = 19 . 4
A = 76

Answer 2

Answer:

A = 76

Step-by-step explanation:

Formula of the area of a triangle: $A=\frac{h*b}{2}$

Formula of a rectangle: $A=l*w$

So starting with the triangle...You know that the height of the triangle is 7, and the base of the triangle is 8 because the base of the rectangle is the same as the triangle's base...

Now using the formula of the triangle...

A = $\frac{7*8}{2}$

= 28

Now find the area of the whole retangle...The length of the rectangle is 13 because 7+6=13; the width is 8

Now using the formula of the rectangle...

A = $13*8$

= 108

Now that you have the areas of both the triangle and the retangle...Do subtraction to find the shaded area...

$108 - 28 = 76$
