5-Minute Check 1

Find the cross products. Construct a Scale Drawing PATIO DESIGN Sheila is designing a patio that is 16 feet long and 14 feet wide. Make a scale drawing of the patio. Use a scale of 0.5 inch = 4 feet. Step 1 Find the measure of the patio’s length on the drawing. Let represent the length. drawing length → actual length → ← drawing length ← actual length Find the cross products. Simplify. Divide each side by 4. Example 3

On the drawing, the length is 2 inches. Construct a Scale Drawing On the drawing, the length is 2 inches. Step 2 Find the measure of the patio’s width on the drawing. Let w represent the width. drawing length → actual length → ← drawing length ← actual length Find the cross products. Simplify. Example 3

Construct a Scale Drawing Divide each side by 4. Simplify. Example 3

Construct a Scale Drawing Example 3

Construct a Scale Drawing Answer: Example 3

A. length = 6 squares width = 5 squares B. length = 9 squares width = 7 squares C. length = 4.5 squares width = 3.5 squares D. length = 5 squares width = 6 squares Example 3
