Question 867137: A rectangle has sides 10 and 12 units. How can the area of a square be computed if its has the same perimeter as the rectangle?
a. add 10 and 12, double the sum, divide by 4, then multiply by 4
b. add 10 and 12, double the sum, divide by 4, then multiply by ? (no.lacking)
c. add 10 and 12, double the sum, divide by 4, then square the quotient
d. add 10 and 12, double the sum, then multiply by 4
I know how to solve for the perimeter of the rectangle:
P of rectangle = 2 (L+W) = 2 (10+12) = 44
but I don't know how to compute for the area of the square using the perimeter of the rectangle.
