Area of a Trapezoid
Formula: 1/2(a+b)h
To find the area of a trapezoid, you are asked to add the parallel sides "a" and "b", then multiply with the height, and finally divide by the integer of 2.
Examples
Suppose you have a plot of land that is shaped like a trapezoid, and you need to determine its area to plan for planting grass or installing a patio. The trapezoid has two parallel sides (bases) and the distance between them (height). Let's say the lengths of the bases are 20 meters and 30 meters, and the height is 15 meters. The formula for the area of a trapezoid is:
Area=21×(Base1+Base2)×Height
Using the given measurements:
Area=21×(20meters+30meters)×15meters
Area=21×50meters×15meters
Area=21×750square meters
Area=375square meters
By calculating the area, you determine that the trapezoidal plot of land is 375 square meters. This information is essential for purchasing the correct amount of grass seed, patio materials, or other landscaping supplies.
