Find the area of right angled triangle whose hypotenuse is 15 cm and one of the sides is 12 cm.  Select:
A) 34 cm²  B) 38 cm²  C) 54 cm²  D) 56 cm²  E) 64 cm²
AB² = A54 cm²² - B54 cm²²   = 15² - 12²   = 225 - 144= 
<gadget id="calculator">225 - 144</gadget>
<output>81</output>
81   Therefore, AB= 9   Therefore, area of the triangle = ¹/₂ × base × height   = ¹/₂ × 12 × 9   = 54 cm²   ANSWER : 54 cm²
