Here we have to use the formula of area of trapezoid, which is
[tex] Area = \frac{b_{1}+b_{2} }{2}*h [/tex]
Where b1 and b2 are the two bases and h is the height or the altitude .
It is given that, Area =7.5 , b1 =1 , b2=5, and h is unknown .
[tex] 7.5 = \frac{1+5}{2}*h [/tex]
[tex] 7.5 = 3h => h =2.5 [/tex]
Correct option is the second option .
