Answer:
The expression representing Area of garden is
.
Step-by-step explanation:
Given:
Width of garden = 
the length of the garden is 1 foot longer than the width
Hence length of garden = 
We need to find the expression for area of garden.
Area of rectangular garden can be calculated as length times width.
Framing in equation form we get;
Area of Garden = 
Solving the equation we get;
Area of Garden =
Hence The expression representing Area of garden is
.

Answer:
B. 
Step-by-step explanation:
Let l represent length of rectangle and w represent width of rectangle.
We have been given four formulas for the perimeter of rectangle. We are asked to choose the formula that displays a common student error for finding the perimeter.
We know that perimeter of a polygon is sum of all sides of the polygon. We also know that rectangle is polygon having two sets of equal sides.
The perimeter, P, of rectangle will be sum of its all sides that is:

Combine like terms:

Factor out 2:

Upon looking at our given choices, we can see that formula represented by option B displays a common student error for finding the perimeter.
