Use the image to answer the question. Given the following net, what is the area of the triangular base? (1 point)
A 24 in.^2
B 48 in.^2
C 10 inches
D 8 inches
B 48 in.^2
The area of the triangular base can be calculated by finding the area of the rectangle and subtracting the area of the three smaller triangles.
Area of rectangle = 10 in x 8 in = 80 in^2
Area of each smaller triangle = 1/2 x base x height = 1/2 x 4 in x 6 in = 12 in^2
Total area of all three small triangles = 12 in^2 x 3 = 36 in^2
Area of triangular base = 80 in^2 - 36 in^2 = 48 in^2
Therefore, the correct answer is B 48 in^2.
