Question

Someone please help me

Answer 1

Answer:

Area = 6cm^2

Step-by-step explanation:

Pythagorean Theorem = $a^{2} + b^{2} = c^{2}$

$a^{2} + 3^{2} = 5^{2}$

or

$a^{2} + 9 = 25$

Subtract 9 from 25.

25 - 9 = 16

Square root 16 to get 4.

a = 4

Now to find the area.

Area = 1/2(3*4)

12/2 = 6
