Answer:

The are a is 6

The length of h = 2.4

Step-by-step explanation:

This is a 3 4 5 special triangle so the length of the hypotenuse is 5

The area for a triangle is calculated by multiplying height to the base and that divided by two

Since it's a right triangle we can take any side length as the height and the result wouldn't change

4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :

h × 5 ÷ 2 = 6

5h = 12

h = 2.4
