The length of the hypotenuse of a right-angled triangle is 37 cm and the length of one of its other two sides is 12 cm. What is the area of the triangle?
Explanation:
Using pythagorus theorem,
372 = 122 + (3rd side)2
⇒ (3rd side)2 = 1369 - 144 = 1225
⇒ 3rd side = 35
∴ Area of triangle = 1/2 × 12 × 35 = 210 cm2
Hence, option (c).
