2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.

Circle A is shown with a central angle marked 30 degrees and the radius marked 5 inches.
anyanavicka [17]

The area for a sector of a circle is A=\frac{\theta}{360}*\pi   r^2. If our angle is 30 and our radius is 5, that fits in like so: A=\frac{30}{360}\pi  (5)^2. It appears that the first choice is what we want except you forgot to square all the radii.

1/n^2 and n^-2 are the same, and 16 and 1/16 definitely aren’t the same 4^-2 is just -4 * -4, and because negative * negative = positive, that adds up to being 16.

The answer is 1/16.
