Solution.
"S(large square)=81 (ft^2)."
Let the area of small square is "x ft^2." Then, the area of one rectangle is "2*x ft^2."
The equation of total area is:
"x+2*x+2*x+2*x+2*x=81; \\newline\n9*x=81;\\newline\nx=9."
The area of one rectangle is:
"S(one rectangle)=2*x=2*9=18 (ft^2)."
Let the side of the square is "a." The area of the square is:
"S(square)=a^2; \\newline\na^2=9; \\newline\na=3 (ft)."
Area of the rectangle is 2-dimensional: it has a length and a width.
The length "l" and width "w" of one rectangle are:
"l=2*a=2*3=6 (ft); \\newline\nw=a=3 (ft)."
Answer: "S (one rectangle)=18 (ft^2), l=6 (ft), w=3 (ft)."
