d. 14,28, and 48

Answer 1

If you mean 1/4 the area, then the answer is (a)

Answer 2

Answer is option ' b '. Since -

Sides of the bigger one are 4 times the corresponding sides of the smaller one. Hence sides of the bigger are -

5x4 = 20

7x4 = 28  and

12x4 = 48.

Answer 3

b. 20,28 and 48.

Answer 4

Make a proportion out of it....

put 5 over seven adn 12 over 'x'

5  12

7   x

Cross multiply and you get  5x=84

ahhhh I give up its B
