Question

the length of a rectangle is 2a. the width is 3a-4. find the area of the rectangle in terms of the variable x.

Answer 1

i don't know how to write in terms of x because i don't know the relation between x and a,
but Area of rectangle=lw=(2a)(3a-4) but this is in terms of a

Answer 2

Area = Length * Width

Area = 2a * 3a - 4

Area = 2a(3a - 4)
Area = 6a^2 - 8a

Answer 3

yay i was close! i just left my a off of the 8
