8. Roger is creating designs with pieces of
wood. One piece is an equilateral triangle
with a perimeter of 24 inches. Another piece
is a rectangle with one side the same length
as a side of the triangle. The other side of the
rectangle is 3 inches shorter than a side of
the triangle. Roger places the pieces together
so that one side of the triangle touches a side
of the rectangle that has the same length.
a. What are the dimensions of the triangle?
b. What are the dimensions of the rectangle?
C. Draw a sketch of the composite figure.
d. Find the perimeter of the composite
