Actual Dimensions Word Problems From Maps

Begin with the scale factor sheets, since the later sheets rely on it. For the area sheets, have students find the actual side lengths before they multiply.

Write and solve proportions to find actual lengths from maps and models, from a road map to a model ship. The directions on the page read: Write a proportion in each box, solve it, and write the answer with its unit. An answer key is included.

Yes, both. We made it for 7th grade geometry, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

A scale factor is the number every length is multiplied by to make a scale copy. Divide a side of the copy by the matching side of the original to find it. Find the Scale Factor Between Similar Figures asks students to write the factor and circle enlargement or reduction.

Write a proportion with the scale and the drawing length, then solve for the actual length. With a scale of 5 cm = 4 m, a drawing length of 16 cm is 12.8 m. Actual Dimensions From a Floor Plan uses a home plan with this scale.

Find the actual length and width first, then multiply them. Do not just scale the drawing area by the length scale. Actual Area From a Scale Drawing has students find what 1 square unit stands for.

Multiply each length by the scale factor, then draw the new lengths. Reproduce a Figure at a New Scale uses a grid and scale factors such as 2, 3/2 and 1/2.
