Question

the area of a triangle whose side are 15cm, 25cm and 14cm is
​

Answer 1

Step-by-step explanation:

Area of a triangle =1/2*base*height

but the picture is not given

Cause if the figure is not given then how can we find which is the base and which is the height.

Answer 2

Answer:

the area of triangle = root of (s-a)(s-b)(s-c)

Semiperimeter= a+b+c/2= (15+25+14)÷2 = 54÷2=27

area of triangle = root of (27-25)(27-15)(27-14)

= root of 2×12×13

= root of 4×78

= 2 root 78 cm²
