Okay, so i see that you need help with this question, and it says quadrilateral abcd is similar to quadrilateral efgh.
00:08
The perimeter of abcd is 40, and the perimeter of efgh is 60.
00:15
So b to c is 10, so it wants to know, and it says the area of abcd is 48, so it wants you to find the area of efgh and the length of fg in units.
00:31
Okay, so what i have to do is i have to find my scale factor.
00:34
So 40 times x equals 60.
00:37
So if i divide by 40, x equals 3 over 2, and so then, if my bc is 10, then i'm going to do 10 times 3 over 2, which would be 30 over 2, which is 15...
