Answer:
Each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
Step-by-step explanation:
Make a sketch and find an isosceles triangle formed by the diagonal, shorter base and the lateral side of the trapezoid.
Thus you have the lateral sides of the trapezoid congruent to the shorter base.
Your trapezoid then has the sides of 5:3:3:3 units.
In total, there are 5 + 3 + 3 + 3 = 14 units.
Hence, each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
