Please help !!!!!!!!!!!!!!!!

Answer 1

Answer:

6 in²

Step-by-step explanation:

The formula of an area of a triangle:

$A_\triangle=\dfrac{bh}{2}$

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:

$A_\triangle=\dfrac{(3)(4)}{2}=\dfrac{12}{2}=6\ in^2$

Answer 2

Answer:

6 in 2.

Step-by-step explanation:

Area =  √s(s-a)(s-b)(s-c)

=  √6×(6 - 4)×(6 - 3)×(6 - 5)

=  6 inches 2.
