Exploring Scale Factor Enlargements in KS2 Maths

What is the first step in enlarging a shape by a scale factor?

• Divide each dimension by the scale factor

• Subtract the scale factor from each dimension

• Add the scale factor to each dimension

• Multiply each dimension by the scale factor

If a rectangle has a base of 3 units and is enlarged by a scale factor of 3, what will be the new base length?

• 6 units

• 9 units

• 12 units

• 15 units

What is the new height of a rectangle with an original height of 2 units when enlarged by a scale factor of 3?

• 7 units

• 6 units

• 5 units

• 4 units

What is the result of multiplying the height of 2 units by a scale factor of 3?

• 5 units

• 4 units

• 7 units

• 6 units

When enlarging a shape by a scale factor of 4, what should you do with the original dimensions?

• Divide each dimension by 4

• Multiply each dimension by 4

• Subtract 4 from each dimension

• Add 4 to each dimension

If a shape has a side length of 2 units and is enlarged by a scale factor of 4, what is the new side length?

• 9 units

• 8 units

• 7 units

• 6 units

How do you determine the scale factor of enlargement when given the original and enlarged shapes?

• Compare the areas of the shapes

• Compare the perimeters of the shapes

• Compare the corresponding side lengths

• Compare the volumes of the shapes
