Answer:
The area of this triangle is 72 cm².
Step-by-step explanation:
We know all 3 lengths of this triangle (12, 12, 17), but all we need to answer this question is sides a and b (12, and 12).
The formula to find the area of a triangle is A = bh/2. Substitute b and h for 12 and 12 respectively.
A = (12 * 12)/2
A = 144/2
A = 72 cm²
The area of the triangle is 72 cm².
