For the triangle, you do 1/2*b*h

Where b is the base and h is the height

So, 1/2*9*7 which is 31.5

For the rectangle, we use the formula l*w

Where l is the length and w is the width

So we do 9*12 which is 108

The w e plus both values together to get the total area of the figure

108+31.5 is 139.5 ( which is roughly 139)

So, the answer to your question is option c

Answer:

C) 139.5 cm^2

Step-by-step explanation:

It is C) 139.5 cm^2 because to find the area of the rectangle, we need to multiply (base x height), so 12x9= 108.

To find the area of the triangle, we need to to multiply

(base x height)(1/2). In the picture it shows us that the base of the triangle is 7 and if you look to the right, the height is 9.

So 7 x 9 (1/2)

63 (1/2)

= 31.5

Lastly you add, 108 + 31.5 = 139.5
