Question

which expression can be used to find the area of triangle rst? (8 4) - (5 - 6 - 8) (8 4) - 1/2 (10 + 12 + 16) (8 4) - 1/2 (5 + 6 + 8) (8 4) - (10 + 12 + 16)

Explanation:

Step1: Identify bounding box area

Assume bounding box area is \(8 \times 4 = 32\).

Step2: Calculate outer triangles area

Sum of outer triangle areas: \(\frac{1}{2}(10+12+16)\).

Step3: Compute triangle RST area

Area = Bounding box area - Outer areas: \(32 - \frac{1}{2}(10+12+16)\).

Answer:

B. (8.4) - 1/2(10+12+16)
