Question

The area of the trapezoid is 24 and the bases are 3 and 5. find the height. 3 3.2 6

Answer 1

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 of the trapezoid (B=5).
 b is the smaller base of the trapezoid (b=5).
 h is the height of the trapezoid.
 
 2. You must clear "h" from the formula:
 
 A=(B+b)h/2
 2A=(B+b)h
 h=2A/(B+b)
 

  3. When you susbtitute the values into  h=2A/(B+b), you obtain:
 
 h=2A/(B+b)
 h=2(24)/(5+3)
 h=48/8
 h=6
