the ratio of the length to the width of a rectangle is 4: 11. the rectangle's perimeter is 650 mm. what are the rectangles dimensions?

4

If two triangles are similar, corresponding sides are in proportion. So, we have

Multiply both sides by to get

Expand the left hand side:

Subtract 17.5y from both sides:

Divide both sides by 10.5:

8

Given the ratio

we can deduce

The perimeter of the rectangle is given by

Now we can deduce the value for x:

8

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
