BE2 + AE2 = AB2
252 = 152 + AE2 AE = √(625 - 225) = √400 = 20,
AC = 20 + 20 = 40 cm.
Area of a rhombus = 1/2 * d1d2

A team won 40 percent of its first 30 games in a particular season, and 80 percent of its remaining games. If the team won a total of 70 percent of its games that season, what was the total number of games that the team played? | [
"120",
"60",
"180",
"90"
] | A | 70% is 30%-points above 40% and 10%-points below 80%.
Thus the ratio of "the first 30 games" to "remaining games" is 1:3.
So the team played a total of 30+90 = 120 games.
