Q. Find the Area of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place
  1. Calculate Trapezoid Area: First, we need to calculate the area of the isosceles trapezoid. The formula for the area of a trapezoid is (base1+base2)/2×height(\text{base}_1 + \text{base}_2) / 2 \times \text{height}. Let's say the bases are aa and bb and the height is hh. We plug in the numbers and calculate.
  2. Calculate Semicircle Area: Now, we calculate the area of the semicircle. The formula for the area of a circle is π×radius2\pi \times \text{radius}^2, but since we have a semicircle, we divide it by 22. So, the area of the semicircle is (π×radius2)/2(\pi \times \text{radius}^2) / 2. We find the radius and plug it into the formula.
  3. Find Total Area: We add the area of the trapezoid and the area of the semicircle to get the total area of the figure. This gives us the final answer.
