the answer is 122
Area of a trapezoid= 0.5*(sum of parallel sides)*height
Area of a trapezoid = 0.5*( sum of parallel sides)*height
If the ratio of the lengths is a:b then the areas are in the ratio of the square of these, namely a2:b2The lengths are in the ratio 8:12 ⇒ 2:3Therefore the areas are in the ratio 22:32 ⇒ 4:9So the area of the larger table is 9/4 = 21/4 = 2.25 times the area of the smaller table.
Area of trapezoid: 0.5*(5+3)*3 = 12 square cm
Area: 0.5*(12+14)*9.5 = 123.5 square units
Area = 1/2*(8+12)*9 = 90 square units
Area = 1/2*(14+12)*8 = 104 square cm

Area of a trapezoid measured in square units = 0.5*(sum of parallel sides)*height
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 !
Area = 1/2*(12+20)*5 = 80 square feet
Area = 1/2*(12+20)*5 = 80 square feet
