Question

A prism has a surface area of 350 mm2.

Find the surface area of a scaled image with a scale factor of 2.

Answer 1

You would mulitply the factor by itself
2^2 = 4

then you would multiply the surface area by 4

350 x 4 = 1400 mm^2

Answer 1400 mm^2

Answer 2

Just put an exponent of '2' on the scale factor and multiply it by the surface area.

Scale factor = 2


`\sf2^2\rightarrow4`

Multiply it:


`\sf350*4=1400~mm^2`
