Question

An artist creates a painting that measures 2.5 feet by 5 feet. A buyer requests that a similar painting be created that is related by a scale factor of 1.8. The buyer plans to use a wooden border as the frame of the painting.

How many feet of wood will he need for the border?

Thank you!

Answer 1

He wants the scale factor to be 1.8
So 2.5×1.8=4.5 and 5×1.8=9
And the border would also be known as the perimeter and perimeter is side+side+side+side and so on
9+9+4.5+4.5=27

he will need 27ft of wood for the border.
