Equations can be used to find the dimensions of the picture frame:
Length = 2 +1/2w
and, 2(l+b)=40
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Perimeter = 40 inches.
let the width be w
length= 1/2w+2
So.
Perimeter of rectangle
40= 2 (l+b)
40= 2(0.5w+2+w)
20=1.5w+2
18=1.5w
w= 12
length= 8
