Question

∆ABC =∆ PQR if AB = 6cm BC = 8cm and AC =4cm find PR and also find the perimeter of ∆ PQR​

Answer 1

Given data :- a traingle ABC, AB= 8cm, BC = 6 cm and AC = 4 cm

Find out :- The Perimeter and the area of the triangle A=?

So the required Perimeter of the triangle is P = ( AB + BC + AC)

= (8+6+4)

= 18 cm answers.

To finding out the area we shall use the hero formula here,

Area A = √s(s-a)(s-b)(s-c) but the value of s can be find like this , S = [(a+b+c)/2]

S = 9 cm

A = √9×1×3×5

= 3√3×√5

= 3√15

= 11.61 ²cm

Hope's it's help's you :D
