Question

The area of right triangle is 30 sq cm. If the base is 5 cm, then the hypotenuse
must be:
a) 12 cm
b) 18 cm
c) 13 cm
d) 20 cm​

Answer 1

Answer:

13 cm

Step-by-step explanation:

area of a triangle = 1/2 × base × height

given base = 5 cm and area = 30 sq cm

30 sq cm = 1/2 × 5 × height

height = 30 ÷ 1/2 ÷5

= 30 × 2 × 1/5

= 12cm

Now we know that height is 12 cm

We use pythagoras theorem to find out the hypotenuse

hypotenuse^2 = 5^2 + 12^2

= 25 + 144

= 169

hypotenuse = sq root. 169 = 13

therefore hypotenuse is 13 cm

Answer 2

Answer:

13 cm is the answer of this question.
