Math Problem Statement

find the area of the triangle:

Find the area of the triangle shown in the image.

Solution

The triangle in the image is a right triangle, with the base and height labeled as 3ft3 \, \text{ft} and 4ft4 \, \text{ft}, respectively. The formula for the area of a triangle is:

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

Substituting the given values:

Area=12×3×4=12×12=6ft2\text{Area} = \frac{1}{2} \times 3 \times 4 = \frac{1}{2} \times 12 = 6 \, \text{ft}^2

Final Answer:

The area of the triangle is 6 square feet.
