Answer:
Area= 4,200 square feet
Step-by-step explanation:
If I read your question correctly, I'm assuming the dots (".") mean a multiplication sign ("x").
If they are all being multiplied, use PEMDAS to solve this. First, find to value for any exponents you have (in this case, it's [tex]2^3[/tex] and [tex]5^2[/tex]).
[tex]2^3=2*2*2=8\\5^2=5*5=25[/tex]
Now that you have the values for these two exponents, multiply all the numbers together.
8 x 3 x 25 x 7 = 4,200
