Question

find the area of triangle whose sides are 13cm , 14cm , and 15cm
with herons formula
plzzz solve it fast ​

Answer 1

Answer:

Sides of triangle = 13 cm, 14 cm, 15 cm

Semi-perimeter = 13+14+15/2 = 42/2 = 21 cm

Heron's Formula = √s(s-a)(s-b)(s-c)

Heron's Formula = √21(21-13)(21-14)(21-15)

Heron's Formula = √21×8×7×6

Heron's Formula = √3×7×2×4×7×2×3

Heron's Formula = √7056

Heron's Formula = 84 sq.cm
