Question

Two similar trapezoids have a scale factor of 3:2. The perimeter of the larger trapezoid is 21 yards. what is the perimeter of the smaller trapezoid?

Answer 1

Perimeter Smaller Trapezoid = (Perimeter of Larger Trapezoid) / (Scale Factor)

 

= (21 yards) / (3/2) = (21 yards)*(2/3) = 14 yards
