Q. 33.5( 8 Votes )

The sides of a triangle are 56 cm, 60 cm and 52 cm long. Then the area of the triangle is
A. 1322 cm2

B. 1311 cm2

C. 1344 cm2

D. 1392 cm2

Answer :

a = 56, b = 60, c = 52

s = (a + b + c)/2


s = (56 + 60 + 52)/2 = 168/2 = 84.


Area(Δ) = √s(s-a)(s-b)(s-c)


Area(Δ) = √84(84-56)(84-60)(84-52)


Area(Δ) = √84×28×24×32


Area(Δ) = 1344cm2


Hence, the correct option is (C).
