<span>1. To
solve this problem you must apply the formula for calcúlate the area of a
trapezoid, which is shown below:
A=(B+b)h/2
A is the area of the trapezoid (A=24). B is the larger base </span>of the trapezoid <span>(B=5). b is the smaller base </span>of the trapezoid<span> (b=5). h is the height </span><span>of the trapezoid.
2. You must clear "h" from the formula: </span><span> A=(B+b)h/2 </span> 2A=<span>(B+b)h </span> h=2A/<span>(B+b) </span><span>
3. When you susbtitute the values into </span> h=2A/(B+b), you obtain:
