How The Area of a Triangle Is 54 Square Units. The Base Is 3 Units Longer Than the Height. Find the Base and Height. Actually Works

To solve for the base and height when the area of a triangle is 54 square units and the base exceeds the height by 3 units, we apply the basic triangle area formula:

Key Insights

Area = (base × height) / 2

Let the height be represented as ( h ). Then the base is ( h + 3 ). Substituting into the formula:

( 54 = \frac{(h + 3) \cdot h}{2} )
Multiply both sides by 2:
( 108 = h(h + 3) )
Expand:
( 108 = h^2 + 3h )
Rearrange into standard quadratic form:
( h^2 + 3h - 108 = 0 )

Apply the quadratic formula:
( h = \frac{-3 \pm \sqrt{3^2 - 4(1)(-108)}}{2} )
( h = \frac{-3 \pm \sqrt{9 + 432}}{2} )
( h = \frac{-3 \pm \sqrt{441}}{2} )
( h = \frac{-3 \pm 21}{2} )

Two potential solutions emerge:
( h = \frac{18}{2} = 9 ), or ( h = \frac{-24}{2} = -12 ) — discard the negative value as height cannot be negative.

Final Thoughts

Thus, height is 9 units, and base is ( 9 + 3 = 12 ) units. This confirms the solver’s value through direct algebra, showing how simple reasoning remains powerful in everyday math.
