We have a right trapezoid with parallel sides of 8 centimeters and 20 centimeters. The height is 16 centimeters and the slant side is 20 centimeters. We need to find the area of this trapezoid.
To find the area of a trapezoid, we use the formula: Area equals one half times the sum of the parallel sides times the height. In our case, b1 equals 20 centimeters, b2 equals 8 centimeters, and h equals 16 centimeters.
Let's calculate step by step. First, we identify our values: b1 equals 20 centimeters, b2 equals 8 centimeters, and h equals 16 centimeters. Then we apply the formula: Area equals one half times 20 plus 8 times 16. This gives us one half times 28 times 16, which equals 14 times 16, resulting in 224 square centimeters.
Let's verify our calculation. We have a right trapezoid with parallel sides of 8 and 20 centimeters, height of 16 centimeters, and slant side of 20 centimeters. Using the trapezoid area formula, we get one half times 8 plus 20 times 16, which equals one half times 28 times 16, giving us 224 square centimeters. Therefore, the answer is 224 square centimeters.
To summarize: we solved a right trapezoid problem with parallel sides of 8 and 20 centimeters and a height of 16 centimeters. Using the trapezoid area formula, we calculated one half times the sum of the bases times the height, which gave us 224 square centimeters. Therefore, the final answer is 224 square centimeters.
