Write an equation to represent the situation.

Assuming the width is x, and the length 3x.

#x + x + 3x + 3x = 48#

#8x = 48#

#x = 6#

The rectangle measures 6 by 18. The formula for area of a rectangle is #L xx W#

#A = L xx W#

#A = 18 xx 6#

#A = 108#

The rectangle has an area of 108.

Hopefully this helps!
