Question

find the height ps of pqr traingle​

Answer 1

Step-by-step explanation:

Perimeter=80+60+100=240 cm

Semi Perimeter(s)=240/2cm =120 cm

Using Heron's Formula,

Area of Triangle =√s(s-a)(s-b)(s-c)

Area of Triangle= √ 120(120-80)(120-60)(120-100)

Area of Triangle= √ 120×40×60×20

Area of Triangle =2400cm^2

Now,

Area of Triangle=base × altitude/2

2400×2=100×PS

48cm=PS
