Identify Formula: Question Prompt: What is the area, in square inches, of the trapezoid given?
Extract Values: Step $1$ : Identify the formula for the area of a trapezoid. The formula is $A = \frac{1}{2} \times (b_1 + b_2) \times h$ where $b_1$ and $b_2$ are the bases and $h$ is the height.
Substitute Values: Step $2$ : Extract the values for $b_1$ , $b_2$ , and $h$ from the problem. Assume $b_1 = 5$ inches, $b_2 = 7$ inches, and $h = 4$ inches.
Perform Calculations: Step $3$ : Substitute the values into the formula. $A = \frac{1}{2} \times (5 + 7) \times 4$ .
Compare Results: Step $4$ : Perform the calculations. $A = \frac{1}{2} \times 12 \times 4 = \frac{1}{2} \times 48 = 24$ square inches.
Compare Results: Step $4$ : Perform the calculations. $A = \frac{1}{2} \times 12 \times 4 = \frac{1}{2} \times 48 = 24$ square inches. Step $5$ : Compare the calculated area with the given answer attempt. The calculated area is $24$ square inches, but the answer attempt is $12$ . $43$ square inches.
