Answer 1

Explanation:

ratio a:b

1:2 > Each of the sides can be multiplied by 2 on rect A

>1(2)=2

>5(2) = 10

Ratio Area(A): Area(B)

1²:2² is for the lengths but area is squared so the lengths get squared for area

1:4

YOu can check:

Area(A) = (1)(5) = 5

Area(B) = (2)(10) = 20

You can see B is 4 times as big as A for Area so 1:4 is right
