What do the sides add up to???
.
You can't tell from the information given. Let me explain with a couple of examples.
.
Suppose the rectangle has sides of: length = 7 m and width = 6 m
.
If you multiply these two together you get an area of 42 m^2. And if you add the 4 sides you
get a total of 6 + 7 + 6 + 7 = 26 m
.
Next suppose the rectangle has sides of: length = 42 m and width = 1 m
.
If you multiply these two together you get an area of 42 m^2. But if you add the 4 sides you
get a total of 1 + 42 + 1 + 42 = 86 m
.
This shows that you can't be sure of what the sides are if you are just given the area.
.
Hope this helps you to see that you can't tell the total of the perimeter (total of the sides)
if you are just given the area of a rectangle. You need some other information.
