Answer 1

6 in²

Explanation:

The formula of an area of a triangle:

`A_\triangle=(bh)/(2)`

b - base

h - height

We have the right triangle. One leg is a base and other leg is a height.

Therefore

b = 3in, h = 4in.

Substitute:

`A_\triangle=((3)(4))/(2)=(12)/(2)=6\ in^2`

Answer 2

6 in 2.

Explanation:

Area = √s(s-a)(s-b)(s-c)

= √6×(6 - 4)×(6 - 3)×(6 - 5)

= 6 inches 2.
