Tyson is creating a scale drawing of the area of his school. the rectangular drawing shows the length as 20 inches and the width
Brilliant_brown [7]
If 1 inch is equal to 3 feet so you can say:
20 inches are equal to 20*3 = 60
and 19 inches is equal to 19*3 = 57 
and because the school is rectangular so the area of the school is: 
60* 57 = 3420 :))
i hope this is helpful 
have a nice day

What is the perimeter of triangle DEF
LuckyWell [14K]
Remember that A squared plus B squared equals C squared.

Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.

SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.

3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18

You get the idea. Hope this helps!
