Answer:
300 in²
Step-by-step explanation:
Hello!
Because the diagonal forms right triangles, we can use the Pythagorean Theorem to find the missing length of the rectangle.
a² + b² = c²
- a = leg
- b = leg
- c = hypotenuse
In this case, 25 is c, and 15 is a. We can solve for b using the formula.
Solve for b
- a² + b² = c²
- 15² + b² = 25²
- 225 + b² = 625
- b² = 400
- b = 20
So the missing length of the rectangle is 20. We can find the area by multiplying 15 and 20
The area is 300 in².
