Answer:
666.6667 feet²
Step-by-step explanation:
So.
Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.
Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.
So it's 8000in²
Then we do 8000 in to feet.
Which is ≈ 666.6667feet
btw it asked for feet so we give them FEET
The answer is 11.2
The Pythagorean Theorem says
a^2+b^2=c^2
From the picture, we know one side, and the hypotenuse.
10^2+b^2=15^2
100+b^2=225
b^2=225
Sqrtb^2=sqrt225
b=11.18
Rounded to the nearest tenth it is 11.2
