Math Problem Statement

Calculate the area of a composite shape consisting of a rectangle and a right triangle with the following dimensions: rectangle - length 16 feet, width 8 feet; triangle - base 10 feet, height 12 feet.

Solution

To calculate the total area of the shape in the image, we need to divide it into simpler parts. The figure can be separated into a rectangle and a right triangle.

1. Area of the Rectangle:

  • The dimensions of the rectangle are given as 16 feet (length) and 8 feet (width).
  • The area AA of a rectangle is calculated using the formula: A=length×widthA = \text{length} \times \text{width} Substituting the given values: A=16×8=128square feetA = 16 \times 8 = 128 \, \text{square feet}

2. Area of the Right Triangle:

  • The right triangle has a base of 10 feet and a height of 12 feet.
  • The area AA of a triangle is calculated using the formula: A=12×base×heightA = \frac{1}{2} \times \text{base} \times \text{height} Substituting the given values: A=12×10×12=60square feetA = \frac{1}{2} \times 10 \times 12 = 60 \, \text{square feet}

3. Total Area:

  • The total area of the shape is the sum of the areas of the rectangle and the triangle: Total Area=128sq ft+60sq ft=188square feet\text{Total Area} = 128 \, \text{sq ft} + 60 \, \text{sq ft} = 188 \, \text{square feet}

Thus, the total area of the figure is 188 square feet.
