Question

base of a right angled triangle is 4cm and hypotenuse is 5cm. find it's area.

Answer 1

By hypotenuse theorem H2 = B2+P2
5*5 = 4*4 +P2
25 = 16 +P2
P2 = 25-16
P2 = 9
perpendicular =3 =height
by
1/2 * base * height
1/2 * 4*3
2*3 =6cm

Answer 2

Area of right angle triangle = 1/2 ×b ×h
B=base
H=height
Height is the other side.....

According to the hypotenuse Theorem,
${c}^{2} - {b }^{2} = {a}^{2}$
Where, a= height, b= base and c= hypotenuse
${5}^{2} - {4}^{2} = 25 - 16 = 9$
${a}^{2} = 9$
$a = \sqrt[2]{9}$
$\sqrt[2]{9} = 3.0$
3

H=3

1/2 × 4 × 3= 6

So, the area of the triangle = 6 m^2
