Question

Find the area of the right angled triangle if it's perpendicular is 60 cm and hypotenuse is 61 cm

Answer 1

Answer:

I don't know. sorry

the formula p2 × b2 = h2

60 2 × b2 = 61 2

3600 × b2 = 3712

b2 = 3712 - 3600

b2 = 112

b = 112 root

= 10.583....

Answer 2

Step-by-step explanation:

area of right angled triangle is 1/2*b*h

to find - base

by Pythagoras theorem ,

${b}^{2} = h {}^{2} - p {}^{2}$

$b {}^{2} = 61 {}^{2} - 60 {}^{2}$

$b {}^{2} = 3721 - 3600$

$b {}^{2} = 121$

$b = 11$

so, base = 11

area = 1/2*11*60

= 330
