A rectangle is 8 cm long and 3.5 cm wide. a) Calculate the area of the rectangle.
State the units of your answer.

area = 28 cm²

Step-by-step explanation:

area = 8 x 3.5 = 28 cm²

28 cm²

Step-by-step explanation:

Because the length of the rectangle is 8 and the width is 3.5 cm which we know we that the area is "length x width" so we should multiply both numbers getting 28 cm

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
