Answer 1

Step-by-step explanation:

A=7cm,B=5cm,C=8cm

S=

2

A+B+C

=

2

7+5+8

=10

area=

s(s−a)(s−b)(s−c)

=

10(10−7)(10−5)(10−8)

=10

3

=17.31cm

2

.

Answer 2

Answer:

17.32

Step-by-step explanation:

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

s= (5+7+8)/2

s=10

Area=√10*5*3*2

Area=√300

Area=17.32cm^2
