Question

An isosceles trapezoid has a perimeter of 51.1 miles. Its shorter base measures 1.6 miles and its longer base measures 10.3 miles. The two remaining sides have the same length; what is that length?

Answer 1

Answer: 19.6

Explanation:

The perimeter of an isoceles triangle is (top+bottom+2*sides)

51.1-1.6=49.5

49.5-10.3=39.2

39.2/2=19.6
