Arectangle has a length of 6x +3 units and a width of 8 units. part a: write a simplified expression for the area, in square units, of this rectangle. square units another rectangle has a length of 4x + 2 units and a width of 12 units part b: are the areas of both rectangles the same? explain how you know.

a) A = 48x + 24

b) Yes

Step-by-step explanation:

a) The area of a rectangle is found using A = l*w. Substitute l = 6x + 3 and w = 8 to find the area.

A = (6x + 3)(8) = 48x + 24

b) Repeat the same process with the formula A = l*w. Substitute l = 4x + 2 and w = 12.

A = (4x+2)(12) = 48x + 24

The areas are the same.
