Finding perimeter is simple. All you do is add up all of the side lengths, and bada bing bada boom, you got the perimeter.
The area of the rectangle is 1,440 cm2.
The relation between a and s is given to be:
a = 640s
where,
a = number of acres
s = number of square miles
We are to find the number of acres for 7.5 square miles.
This means, s = 7.5
Using the value in the formula, we get:
a = 640 x 7.5 = 4800 acres
So the answer to this question is option B
The answer is i don't know you should search it up it seems pretty hard
