Answer:
The area of the quadrilateral is 12 square feet. (B)
Step-by-step explanation:
To find the area of a triangle, we use the formula (L x W) / 2
The bottom triangles are both the same size, so we only need to find the area of one. The width of the triangle needs to be divided by two because we only need to know half of the big triangle on the bottom at the moment. So we have (3 x 2) / 2 = 3. We can then multiply that by two and the area of the bottom triangle is 6. To solve for the top, (3 x 4) / 2 = 6. We can then add together the top and the bottom to get B, 12 square feet.
