Which expression gives the area of the red rectangle.

a

(a + b)(c + d)

b

(a + b)(c - d)

c

(a + b)(c + d) - c(a + b) - bd

d

(a + b)(c + d) - d(a + b) - bd

Assumption:

The figure is not given in the question so in absence of figure it is difficult to tell exact answer. However in order to solve it we assume that Lenght of RED rectangle is (A+B) and width is (C+D).

The correct answer is A. (A+B)(C+D).

Step-by-step explanation:

The formula to calculate area of rectangle is = Lenght * Width

Area = L* W

(Putting values)

Area = (A+B)(C+D)

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

c. 1,233 miles
