Question

if the three sides of a triangle are 5cms ,3cms and 4cms the area of triangle is ​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

We know,

Area of △ = √[s(s - a)(s - b)(s - c)]

s = ½(a + b + c) = ½(5 + 3 + 4 cm) = 6 cm

$∴$ Area = √[6(6 - 5)(6 - 3)(6 - 4)] cm²

$\leadsto$ √[6 × 3 × 2] cm²

$\leadsto$ √(6)² cm²

$\leadsto$ 6 cm²

Similar formula:-

Formula of Brahmagupta:-

√[s(s - a)(s - b)(s - c)(s - b)]

Can be applied in case of finding the area of cyclic quadrilaterals.
