Answer 1

Answer:

answer for the given problem is given

Answer 2

Ans:- We can find area of triangle by using heron's formula:-

= By using heron's formula

Ans:- Let 8cm = a, 11cm = b, 13cm = c

S = 1/2(a+b+c) ( S stands for Semiperimeter of triangle)

S = 1/2(8+11+13) = 1/2×32 = 16

Now,

Area of triangle = √s(s−a)(s−b)(s−c)

= √16(16-8) (16-11) (16-13)

= √16×8×5×3

= √1920 = 43.8cm^2

or 8√30 cm^2
