Question

If the base of a right angled triangle is 15 cm and it's hypotenuse is 25 cm, then find its area

Answer 1

Step-by-step explanation:

base(b) = 15cm

hypotenuse(h) = 25cm

so,

area= ½× b × h

area = ½× 15 × 25

area = 187.5cm²

Answer 2

Step-by-step explanation:

given:

• Base=15cm
• hypotenuse=25cm
• area?

formula:

• area=1/2(b*h)

hypotenuse=sqrt{b ^{2} + {h}^{2} }

ans:

height=√[625-225]

=√[400]=20

area=1/2(15*20)=150cm^2
