Question

Heron's formula find the area of triangle whose sides are 12cm,10cm and 16cm​

Answer 1

Step-by-step explanation:

sides of Triangle are 12 cm. 10 cm and 16 cm.

Let a= 12 cm

b = 10 cm

c = 16 cm

Semi perimeter = ( a+b+c) /2

S = 12 + 10 + 16 /

S = 38/2

S = 19

So ,Using the herons formula

√s(s-a)(s-b)(s-c)

√19 (19-12) (19-10) (19-16)

√ 19(7) (9) (3)

= √3591

= 59.92
