Question

In the figure, ABCD is a rectangle. If the area of triangle AEB is 12, what is the area of triangle ACD?

Answer 1

@sakigirl are u attempting any of these urself?

Answer 2

Was wondering the same.

Answer 3

@genius12 Yep! These are the ones that I do not understand. I have SAT homework, and I'm posting the ones that I didn't get.

Answer 4

AB=DC

Answer 5

try to figure out of the ratio of the heights of AEB and ACD

Answer 6

.............you can just use ratios.......

Answer 7

Call the length 'x' and width 'y'. Then the area of AEB is given by:\[\bf Area \ of \ \triangle AEB=\frac{ xy }{ 4 }\]Now the area of the triangle BEC would be given by:\[\bf Area \ of \ \triangle BEC =\frac{ xy }{ 4 }\]As you can see they're equal.
