As seen in the diagram below, Madelyn is building a walkway with a width of a feet to

julsineya [31]

Applying the area of a rectangle, the width of the walkway (x) is: 4 feet.

<h3>What is the Area of a Rectangle?</h3>

Area of a rectangle = (length)(width)

Total area of the pool and walkway = 300 sq. ft

Length of the pool and walkway = 12 + 2x

Width of the pool and walkway = 7 + 2x

Thus, we will have the equation of the total area as:

(12 + 2x)(7 + 2x) = 300

4x² + 38x + 84 = 300

4x² + 38x + 84 - 300 = 0

4x² + 38x - 216 = 0

Factorize

(x - 4)(2x + 27) = 0

x = 4

x = -27/2

The width, x, cannot be negative, so, the width of the walkway (x) would be 4 feet.

Math's the devil but help plz

erma4kov [3.2K]

Using the apothem, a, and the perimeter, p, the area, A, of a regular polygon is

$A = \dfrac{pa}{2}$

You need to calculate the area of the octagon and subtract the area of the square.
The perimeter is 8 times the side.

$A = \dfrac{pa}{2} - s^2$

$A = \dfrac{8 \times 13 \times 15.69}{2} - 13^2$

$A = 815.88 - 169$

$A = 646.88$
