Question

find the area of the triangular whose sides 5cm,12cm,13cm resp. if the height of an equi.∆ meters 9cm than find its area?​

Answer 1

Answer:

Step-by-step explanation:

Here Sides are - 5 cm, 12 cm and 13 cm.

So, s = (a+b+c+)/2 where a,b, and c are sides of triangle

s = (5+12+13)/2 = 30/2 = 15

Area =√ 15( 15-5)(15-12)(15-13)

So, Area = 30

the smallest height will be on the largest base. So here the largest side is 13 cm.

So by area formula we have

Area = 1/2 ×base ×height

But area = 30

so, 30 = 1/2 × 13 ×height

height = 60/13 = 4.615 cm

hope so correct !!!!!!!!!!!!!!!!!
