6-27.

For each generic rectangle fill in the missing parts. Write an equation showing the area as a sum equals the area as a product.

Generic rectangle top edge left blank
top edge middle $+3$
top edge right blank
interior left $xy$
interior middle blank
interior right $y^2$
bottom edge left $x$
bottom edge middle blank
bottom edge right blank

Hint (a):
The product of the dimensions of the rectangle is equal to the area.
Generic rectangle top edge left blank
top edge middle $3$
top edge right blank
interior left $xy$
interior middle blank
interior right $y^2$
right edge $y$
bottom edge left $x$
bottom edge middle $3$
bottom edge right blank
Answer (a):
$y\left(x + 3 + y\right) = xy + 3y + y^{2}$

Generic rectangle interior top left $x^2$
interior top right blank
interior bottom left $8x$
interior bottom right blank
bottom edge left blank
bottom edge right $+3$

Hint (b):

Follow the same step as (a).
Generic rectangle interior top left $x^2$
interior top right blank
interior bottom left $8x$
interior bottom right blank
bottom edge left $\color {red}x$
bottom edge right $3$
