Question

a) The length of hypotenuse of a right angled triangle is 13 cm
and the length of another side is 5 cm. Find its area.​

Answer 1

answer :

Hypotenuse(H) is 13cm.

One side is 5cm.

Use Pythagoras theorem :-

H^2 = L^2 + B^2

Solving it you will find other side as 12cm.

Now area of triangle is 1/2(5x12) = 30cm^2.

Hence area of triangle is 30cm^2.

Answer 2

given h= 13 cm

and b = 5 cm

in right angle triangle , we konw that

.

p= 12

now area of right angle triangle

p*b/2= 30 cmsquare
