Question

JJ's new drawing 10 in x 14 2/3 in but now he wants to make it bigger What are the dimensions if he multiplies by a scale of 2 1/2 Will his new drawing be smaller or larger than the original drawing

Answer 1

Let's multiply

Length

• 10×2 1/2
• 10×5/2
• 5(5)
• 25in

Breadth

• 14 2/3×5/2
• 44/3×5/2
• 22/3(5)
• 110/3 in

Larger

Answer 2

• 25 in x 36 2/3 in

Explanation:

Since the scale factor is greater than 1 the new drawing will have greater dimensions thus will have larger area.

The new dimensions:

• 10 * 2 1/2 = 10 * 5/2 = 25 in and
• 14 2/3 * 2 1/2 = 44/3 * 5/2 =110/3 = 36 2/3 in
