Janice's calculation is incorrect because:
A: The Two Triangles have different areas
B: The Dimensions of one Triangle are not given
C: The Widths of two triangles were not given
D: The Rectangles are not all the same Size
Janice should find the area of the two triangles by calculating:
A: (0.5 x 10 x 12) + (0.5 x 10 x 13)
B: (0.5 x 10 x 12) + (0.5 x 13 x 12)
C: 0.5 x 10 x 12 x 2
D: 0.5 x 10 x 13 x 2
She should find the area of the three rectangles by calculating:
A: 10 x 6 x 3
B: 13 x 6 x 3
C: (10 x 6 x 2) + (13 x 6)
D: (13 x 6 x 2) + (10 x 6)
The total surface area is:
A: 300
B: 318
C: 336
D: 341
