Assuming the height is 13 inches (not 13 feet or something else), Area = 0.5*(12+14)*13 = 169 sq inches.
Area = 1/2*(14+12)*8 = 104 square cm
Area = 1/2*(14+12)*8 = 104 square cm
If the blocks are 12 inches x 12 inches then each block measures 1 square foot. An area of 14 feet x 14 feet has a surface area of 196 square feet, so it would require 196 of the 12" x 12" blocks to cover it.
The area of ANY trapezoid is [ 1/2 times (height) times (one base plus the other base) ].Knowing that, you can now find the area of not only that particular trapezoid, but ofevery trapezoid that you ever encounter for the rest of your life. The formula is notexpected to change. You are empowered !
