This caption needs to be 20 words long, but my picture explains everything lol... i hope this helps :)
A²+b²=c²
a=b because it has 2 45° angles and one 90 so it is isosceles right triangle
∴ a² + a² = c²
2a²=24²
2a²=576
a²=288
a=√288
a=16.97056275
Therefore. With A=1/2bh
A=(1/2) * 16.97056275 * 16.97056275
= (1/2) * 288
= 144
144 ft²
The difference between a number divided by 3 and 4 is 20.
- = 20
multiply by 12
4n - 3n = 12(20)
n = 240 is the number
