Question

Find the area of the rectangle.
LENGTH: x+3     WIDTH: 2x+1
a. 2x2 + 6x + 3
b. 8x + 3
c. 2x2 + 7x + 3
d. 9x

$$A = l \times w$$
A=Area of the rectangle
l=length
w=width

anonymous · Answer

area is l*w = (x+3) (2x+1)
then you just multiply the two:
2x^2+7x+3

anonymous · Answer

c

anonymous · Answer

therefore, in this case,
$$A = (x+3)(2x+1)$$
After, expand the brackets and get your answer.....

b. (2x^2 + 3x - 12)in.^2
c. (2x^2 - 8x - 12)in.^2
d. (2x^2 - 5x - 12)in.^2
