Answer:
84 m²
Explanation:
If you mention "hypotenuse," I automatically assume that this is a right triangle. We can find the length of the third side using the Pythagorean Theorem: 7² + x² = 25², or x² = 625 - 49 = 576.
Then the 3rd side (which is also the height of the triangle) is x = √576 = 24.
The base of this triangle is 7 m and the height is 24 m.
The area is thus:
A = (1/2)(base)(height) = (1/2)(7 m)(24 m) = 84 m²
