4-70.

On graph paper, draw any quadrilateral. Then enlarge (or reduce) it by each of the following ratios. Homework Help ✎

The quadrilateral below will be used to show you how to do this problem.

For your homework, use a different quadrilateral and follow the steps and hints shown here.

To enlarge it by 4:1, each side must be four times as long.

In this case, each side of the parallelogram must be four units long.

We can start by making this a ratio in the form of

since our original quadrilateral has sides of length 1 unit. Thus we find the new ratio of

This means each side of the new quadrilateral must be 3.5 times longer than that of the original.
