Answer:

h = 4.5 units

Explanation:

The area (A) of a triangle is calculated as

A =
(1)/(2) bh ( b is the base and h the height )

Here A = 6.75 and b = 3 , then


(1)/(2) × 3h = 6.75

1.5h = 6.75 ( divide both sides by 1.5 )

h = 4.5

we have

base [b]=3 units

height [h]=x units

area of triangle =6.75 square units

we have

area of triangle =1/2 b×h

6.75 square units =1/2×3×x

x=6.75×2/3=4.5units

so height is 4.5 units.
