The ratio of the top to the bottom of a trapezoid is 3 / 5. The top is 1 meter shorter than the bottom, and the bottom is 25% higher. What is the area of this trapezoid?

The ratio of the top to the bottom of a trapezoid is 3 / 5. The top is 1 meter shorter than the bottom, and the bottom is 25% higher. What is the area of this trapezoid?

Set the top and bottom to be 3x meters,
3x+1=5x
x=0.5
H=5x(1-25%)=3/16
S=(1.5+2.5)×3/32=3/8
