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
Answer:
22
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out expression
40 - 2 × 3²
Step 2: Exponents
40 - 2 × 9
Step 3: Multiply
40 - 18
Step 4: Subtract
22
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!
