Question

Q-1.) The sides of a triangle are 56 cm 60 cm and 52 cm long . Find the area of a triangle .​

Answer 1

Answer:

Area of a Triangle= 1/2×b×h

we can't use the property as we don't know the height or base

so finding it by Heron's Formula

=√s(s-a)(s-b)(s-c)

where S is the sum of all sides /Perimeter divided by 2

(56+60+52)/2=84

√s(s-a)(s-b)(s-c)

√84(84-56)(84-60)(84-52)

√84×28×24×32

=√(2×3×7×2)(2×2×7)(2×2×2×3)(2×2×2×2×2)

=2×2×2×2×2×2×7×3

=1344 cm²

hope it helps
