Presentation transcript:

On a floor plan of her room, the length of Hailey’s bed is 3 inches. If the scale of her floor plan is inch = 1 foot, what is the actual length of her bed?

Objectives SWBAT construct scale drawings given a scale and actual measurement.

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. drawing length → actual length → ← drawing length ← actual length Find the cross products. Simplify. Divide each side by 4. Step 1Find the measure of the patio’s length on the drawing. Let represent the length. On the drawing, the length is 2 inches.

Construct a Scale Drawing Step 2Find 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.

Divide each side by 4. Simplify.
