Answer: 72 cm²
Step-by-step explanation: 1/2(base)(height) is the formula to find the area of a triangle. To find the area of the bigger triangle we substitute 10 cm for the base and 6 cm for the height.
1/2(10)(6)
1/2(60)
30 cm²
since we have two of the same triangles, we double that
we also have a smaller triangle. 14-10=4 which is the base of the smaller triangle.
1/2(4)(6)
1/2(24)
12 cm²
now, we add everything
60 cm² + 12 cm² = 72 cm²
