Answer:
180 in²
Step-by-step explanation:
Smaller octagon : larger octagon = 5 : 9
The area of the smaller octagon is 100 in2. Find the area of the larger octagon
Let x = area of larger octagon
Area of smaller octagon : Area of larger octagon = 100 in² : x in²
5 : 9 = 100 in² : x in²
5/9 = 100/x
Cross product
5 * x = 9 * 100
5x = 900
x = 900/5
= 180
x = 180 in²
First you need to set this problem up as a cross multiply fraction set (actually forgot the name of it so I described it as that).
10/15 * 30/x
Solve for X
450 = 10x
Simplify
45 = x

The ladder forms the hypotenuse of a right triangle. Solve for a
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 9^2 = 18^2 </span>
<span>a^2 + 81 = 324 </span>
<span>a^2 = 243 </span>
<span>a = 15.589 = 15.6 feet</span>
