Answer:
The formula you provided is for the area of a trapezoid. A trapezoid is a quadrilateral with one pair of parallel sides. The formula states that the area (A) of a trapezoid is equal to half the sum of the lengths of its parallel sides (b1 and b2) multiplied by its height (h).
Using this formula and the values you provided, we can calculate the area of the trapezoid:
A = ((8 cm + 6 cm) * 4 cm) / 2 A = (14 cm * 4 cm) / 2 A = 56 cm² / 2 A = 28 cm²
So, according to these calculations, the area of this trapezoid is 28 square centimeters.
