The semi perimeter of a triangle is 132 cm and the product of the difference of semi perimeter and three respective sides in cm is 13200. Find the area of the triangle.​

Answer»

ong>Answer:

semi-perimeter s=(a+b+c)/2

s = 132 CM and

(s-a)(s-b)(s-c) = 13200 cm²

Therefore, according to the Heron's formula,

Area of the triangle = √s(s-a)(s-b)(s-c)

Now, substituting the VALUES, we get

Area = √132×13200

= √132×132×100

= √132×132×10×10

Area of the triangle = 132×10

Area = 1320 cm²
