What is the area of a trapezoid whose bases are 8cm and 12cm and has an area of 140cmsquare?
You already know the area do you mean what is the height?
If so then it is worked out like this:-
1/2*(8+12)*height = 140
Multiply both sides by 2 and add up the numbers in the brackets
20*height = 280
Divide both sides by 20 to find the height:
height = 14 cm
Check: 1/2*(8+12)*14 = 140 square cm
