Question

Find the area of a right-angled triangle
(1) perpendicular - 60 cm and hypotenuse - 61 cm​

Answer 1

Answer:

330  cm sq

Step-by-step explanation:

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

so first we have to find base    

so we will follow pythogoreans theoram

b^2   = h^2 - p^2  

b^2 = 61^2 - 60^2

b^2 = 3721 - 3600

b^2 = 121

b = 11

base   = 11

Area =1/2(Base × Perpendicular)    

Area =1/2(60×11)

Area =330 cm sq.
