Trapezoid bases

In a trapezoid, the difference is a base of 6 cm. Calculate the lengths of the bottom of a trapezoid when its height is 8 cm and the area of the trapezoid is 168 cm square.

Final Answer:

a =  24 cm
c =  18 cm

Step-by-step explanation:

h=8 cm S=168 cm2  ac=6 S=(a+c) 2h 168=(a+c) 28  168=(a+c) 8/2  ac=6 8a+8c=336  Pivot:Row1Row2  Row281 Row1Row2 2c=36  c=236=18 a=83368c=83368 18=24=24 cm  a=24 c=18
