a trapezoid has an area of 4 square units and a height of 1 unit what are the possible lengths and bases

Answer 1

recall that area of trapezoid is
A = (b1 + b2)*(h/2)
where
b1 and b2 are the bases of trapezoid
h is the height
substituting,
4 = (b1 + b2) * (1/2)
8 = b1 + b2
now we list two number whose sum is 8:
1 and 7
2 and 6
3 and 5
4 and 4
these are the possible lengths of bases.

hope this helps~ :)
