Question 988784: An artist want to frame a square painting with an area of 400 square inches. She wants to know the length of the wood trim that is needed to go around the painting. If x is the length of one side of the painting, what equation can you set up to find a length of the side? Found 2 solutions by Boreal, macston:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! It is a square painting of 400 sq in,
All sides are equal in a square, and the side length is the square root of the area.
The square root of 400 sq in is 20 inches.
The perimeter is 4 times that or 80 inches.

Area of a square= side squared
x=length of side
.
Perimeter of a square=4 x side
Perimeter of painting=4(20in)=80 inches
Answer: To frame the painting she needs:
80 inches + 8 times the width of the trim
(The extra over the perimeter is for the mitered corners.)
