How do i find the area for number 4?
2 answers:
You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:
Area = Length x Width
A = L x W
To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them
<h3>Answer: 41 cm^2</h3>
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
- The bottom rectangle has area of 4*8 = 32 cm^2
- The top rectangle has area of 3*3 = 9 cm^2
The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".

Answer:
Step-by-step explanation:
(Assuming the den is a rectangle)
Let be the length of the den. Because the length is 10 feet longer than the width, the width of the den can be represented as
.
The area of a rectangle is given as , therefore we can form the following equation:
Expanding this, we have:
This factors into , therefore
.
Because -11 is extraneous, the length of the den is feet and the width is
. Thus, the dimensions of the den are
.
