Answer:
A ≈ 117.3 cm²
Explanation:
Pythagorean Theorem: a² + b² = c²
Area of a Triangle: A = 1/2bh
If Triangle A ≅ Triangle B, then the bottom side length of A would be 11 cm and the hypotenuse will stay 24 cm.
Step 1: Find the vertical leg of A
11² + b² = 24²
121 + b² = 576
b² = 455
b = 21.3307 cm
Step 2: Find area of A
A = 1/2(11)(21.3307)
A = 1/2(234.638)
A = 117.319
A ≈ 117.3 cm²
