Answer: F

Step-by-step explanation:

This is basically like 2 rectangles. Find the area of both and add them together.

Remember that the area is $l$ x $w$ .

Area of Rectangle 1: $l$ = 7, $w$ = 14

14 x 7 = 98 $cm^{2}$

Area of Rectangle 2: $l$ = 5, $w$ = 14

14 x 5 = 70 $cm^{2}$

Add the areas together: 98 $cm^{2}$ + 70 $cm^{2}$ = 168 $cm^{2}$

I cant believe how bad my brother, Reuben, is at growing things. He bought a whole bunch of plants at the nursery the other day.

Answer:

68 plants.

Step-by-step explanation:

Let x represent the number of plants that Reuben bought from the nursery.

We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be $x-5$ .

We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be $\frac{2}{9}(x-5)$ .

Further a rabbit came and ate ½ of what was left. So number of plants left would be $\frac{\frac{2}{9}(x-5)}{2}=\frac{2}{9\times 2}(x-5)=\frac{1}{9}(x-5)$ .
