Answer:
24.9
Step-by-step explanation:
See the image below:)
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 =

D both are right triangles
Well ven diagrams help you visually compare and contrast two figures. They helps you note the similarities and the differences between two items. Hope this helps!
Total area = 4 × 8.5 × 11 = 374 in²
374 in² = 374/144 = 2.597 ft²
