Please help this is so confusing!!!

Answer:
A; scale = 1/4, length = 1, height = 3/4.
B; scale = 2.5, length = 5, height = 15.
C; scale = 3, length = 6, height = 6.
Step-by-step explanation:
for A.
if one scale which means length of one small square is 1/4. we can see that the base of A has 4 scales with a value of 1/4. so to get the length you multiply the scale which is number of scales in the base which 4 if you look at the base. 1/4 x 4 is 1. to find height you multiply the scale with the number of scales upward which you can see has 3 scale so height is 1/4 x 3 = 3/4. you apply the same method to the other two to get the answer.
