CPM Homework Help : CC1 Problem 5-35

Draw a rectangle. Label the lengths of the sides. Enlarge it so that the ratio of sides of your new rectangle to the original one is $\frac { 5 } { 2 }$ . What are the new dimensions?

Hint 1:

Fitzwilliam was asked to draw two squares with the ratio of sides $2:5$ .
As you can see, each side of the original square is $1$ unit, and each side of the new square is $2.5$ units.
Can you find a way that Fitzwilliam may have enlarged his squares?
$\array{ 1\\ \ \ \ \bbox[lightgreen, 4px, border:3px green] {\phantom{\int x}}\ \ 1 }$ $\array{ 2.5\\ \qquad \bbox[lightgreen, 30px, border:3px green] {\phantom{\int x}}\ \ 2.5 }$

Hint 2:

Fitzwilliam multiplied each side by $2.5$ , or $\frac{5}{2}$ , in order to enlarge his square.
Do you think this will work for your rectangles?
Make sure your drawings are neat!
