If you assume that 2.5 refers to the scale factor, you multiply each linear measurement by 2.5. This includes the width, the length, and - if you want to use it to construct your new rectangle - the diagonals. It also happens to include the perimeter, but you probably won't need that to construct the rectangle.

The scale "4 cm = 1 m" is a factor of 1:25 (1/25th scale). 1m/.04m = 25

Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.

1 : 1.25

The area of rectangle is : 100.0

No, 5 is a factor of 25.

Yes. 25 is a factor of 75.

Factor: 9x2 - 25.

No, 25 is a factor of 50.

(a(rectangle))(.25)+(a(rectangle))(.25)=(a(rectangle))(.5)I REALLY hope you can read algebraic expressions, 'cause if you can't....the above equation will make no sense to you.
