Question

⊿ABCis a right angled triangle in which

∠ = 90°

and AB = 40cm and AC = 41cm then find

its area​

Answer 1

Answer:

answer is 180.

angle B = 90°

AB = 40

AC = 41

BC = (b)2 = (h)2 - (p)2

= (41*41) - (40*40)

= 1681 - 1600

(b)2 = 81

b = 9

area of right angle is 1/2 * b * h

= 1/2 * 40 * 9

= 20 * 9

= 180
