The expressions for the width, W, and area, A, of the rectangle in terms of L are:
- W =
- L - A =
The expression for the perimeter of a rectangle is given as:
P = 2(L + W)
where L is its length and W its width
a. Given that the perimeter of the rectangle is 13 feet, then;
13 = 2(L + W)
divide through by 2
= L + W
So that;
W = - L
The required formula for the width as a function of L is: W = - L
b. Area of a rectangle can be expressed as;
A = L * W
substitute the expression for width in that of area to have
A = L * ( - L)
= L - 
A =
The expression for the area A is: A =

Answer: total length of frame material is 3.2 meters
Step-by-step explanation:
The perimeter of an object or a plane shape is the distance around the object of plane shape.
Mila plans to frame a poster she bought at a concert. The total length of frame material that she needs would be the perimeter of the rectangular frame. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
The frame will be rectangular with a base of 0.65 meters and a height of 0.95 meters. Therefore,
Perimeter = 2(0.65 + 0.95)
= 3.2 meters
Answer:
The brother would be 13
