Explanation:

Step1: Calculate Area of Triangle A

Use triangle area formula $\frac{1}{2} \times base \times height$
$\frac{1}{2} \times 8 \times 25 = 100$

Step2: Calculate Area of Rectangle B

Use rectangle area formula $length \times width$
$55 \times 25 = 1375$

Step3: Calculate Area of Triangle C

Use triangle area formula $\frac{1}{2} \times base \times height$
$\frac{1}{2} \times 17 \times 25 = 212.5$

Answer:

The area of triangle A is 100 square inches.
The area of rectangle B is 1375 square inches.
The area of triangle C is 212.5 square inches.
