Dimensions and Proportionality in Rectangles

Mr. Masonette introduces a word problem involving scale factor with rectangles. He explains how to determine if a rectangle is a scaled copy of another by comparing their dimensions as ratios. The video evaluates several options to identify which rectangles are scaled copies of the original. The lesson concludes with verification of results and a reminder to subscribe for more tutorials.

What is the main objective of the problem discussed in the video?

• To identify the color of Rectangle A

• To calculate the perimeter of Rectangle B

• To determine the scale factor between rectangles

• To find the area of Rectangle A

What are the dimensions of Rectangle A?

• 20 cm by 5 cm

• 15 cm by 5 cm

• 25 cm by 10 cm

• 30 cm by 10 cm

How is the ratio of Rectangle A expressed?

• 2:1

• 3:1

• 4:1

• 5:1

Why is Option A considered a scaled copy of Rectangle A?

• Its width is four times its length

• Its length is four times its width

• Its dimensions are identical to Rectangle A

• Its length is twice its width

What are the dimensions of Option A?

• 10 cm by 2 cm

• 6 cm by 1.5 cm

• 18 cm by 4.5 cm

• 11 cm by 4 cm

Why is Option B not a scaled copy of Rectangle A?

• Its length is three times its width

• Its dimensions are identical to Rectangle A

• Its length is five times its width

• Its width is five times its length

What are the dimensions of Option B?

• 6 cm by 1.5 cm

• 10 cm by 2 cm

• 18 cm by 4.5 cm

• 11 cm by 4 cm

Why is Option C not a scaled copy of Rectangle A?

• Its width is four times its length

• Its length is not four times its width

• Its length is twice its width

• Its dimensions are identical to Rectangle A

What are the dimensions of Option C?

• 6 cm by 1.5 cm

• 10 cm by 2 cm

• 18 cm by 4.5 cm

• 11 cm by 4 cm

Why is Option D considered a scaled copy of Rectangle A?

• Its length is twice its width

• Its length is four times its width

• Its width is four times its length

• Its dimensions are identical to Rectangle A
