Ab=9 cm,ac=4 cm,bc=6 cm,and m what is the approximate area of this triangle?
. this is time ! will mark

9.562

Step-by-step explanation:

Use the Heron’s Formula to find the area of a triangle when all three sides are known (SSS). In the formulas below, S represents the semi-perimeter of the triangle, and ABC are the three given sides.

You must first know the semi-perimeter (S) before you are able to calculate the area.

S= 1/2 (A+B+C)

Area = √S(S-A)(S-B)(S-C)

In your case:

semi perimeter

= 1/2 (9+4+6)

= 19/2

= 9.5

Area

= √9.5(9.5−9)(9.5−4)(9.5−6)

= √91.4375

= 9.562
