Question

Find the area of a right triangle whose hypotenuse is 13 cm and one side is 5cm

​

Answer 1

Answer:

12

Step-by-step explanation:

hyp square = base square  + altitude square

13 square = b sq + 5 sq

169 = b sq + 25

169 - 25 = b sq

144=b sq

square root of 144 is 12

so, 12 = base

Answer 2

Answer:

30cm²

Step-by-step explanation:

Area of a right angle triangle = HALF INTO BASE INTO HEIGHT

BY PYTHAGORAS, H²=B²+P²

H=13cm

One side(Either B or P,let it be B) =5cm

• 13²=5²+P²
• 169-25=P²
• 144=P²
• 12=P

Area=½ X 5 X 12

=5X6

=30cm² Ans.
