A steel plate is in the shape of a right triangle. The lengths of the legs are in the ratio 5:12. If the hypotenuse is 13 m, what is the area?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 30 m2.
Ratio = 5 : 12
Triplet = 5, 12, 13
So, hypotenuse = 13 m
So, legs = 5 m and 12 m
Area = × 5 × 12 = 30 m2
