Answer:
25
use the formula for hypotenouse of a triangle to find the diangles as if they were the hypotenouse so 5 squared plus 10 squared is 25 plus 100 which is 125 which has the square root 11.2. so now you have the length (longer side) so for the width it's 1 squared plus 2 squared which is 1 plus 4 is 5 so the square root of 5 is about 2.2 so that's the width (shorter side) so now for the area it's 11.2 (length) times 2.2 (width) which is about 25. hope this hopes let me know if you have a question
