Math Problem Statement

Find the height of the triangle given the base as 8 inches and the area as 24 square inches.

Solution

To solve for the height of the triangle, we use the formula for the area of a triangle:

Area=12×base×height.\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}.

Step 1: Substitute the given values

From the problem, we know: Area=24in2andbase=8in.\text{Area} = 24 \, \text{in}^2 \quad \text{and} \quad \text{base} = 8 \, \text{in}.

Substitute into the formula: 24=12×8×height.24 = \frac{1}{2} \times 8 \times \text{height}.

Step 2: Simplify the equation

First, simplify the multiplication: 24=4×height.24 = 4 \times \text{height}.

Step 3: Solve for height

Divide both sides by 4: height=244=6in.\text{height} = \frac{24}{4} = 6 \, \text{in}.

Final Answer:

The height of the triangle is: 6in.\boxed{6 \, \text{in}}.
