Q. Find the Area of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place
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. Let's say the bases are a and b and the height is h. We plug in the numbers and calculate.
Calculate Semicircle Area: Now, we calculate the area of the semicircle. The formula for the area of a circle is π×radius2, but since we have a semicircle, we divide it by 2. So, the area of the semicircle is (π×radius2)/2. We find the radius and plug it into the formula.
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.
