To find the area of this kind of shape, you need to divide the shape into parts. Let’s cut the top. So we have a small rectangle and a big rectangle now.
Let’s solve for the smaller one first.
The area of a rectangle is length x width. So the length is 16cm and the width is 3cm.
16 • 3 = 48cm
The area of the smaller rectangle is 48cm.
Now let’s solve for the larger rectangle.
The length is 22cm. You find that by doing 16+3+3. The width is 11cm.
22 • 11 = 242cm.
The area of the larger rectangle is 242cm.
Now to find the area of the whole thing, add the area of the rectangles.
48cm + 242cm = 290cm.
The area of the polygon is 290cm.

How do i write 2 perfect squares that each have a value greater then 100 and less that 200

nordsb [41]

Just start squaring numbers! 10² = 100, so to find perfect squares bigger than that, we can just increase the base. 11² = 121, and 12² = 144, and both of those meet our requirements, so we could choose 121 and 144 as our examples.

Computing the ratio of raisins to ounces, it is found that due to the higher computed ratio, brand B advertises the greatest ratio of raisins per ounce.

---------------------------

For brand A, there are 60 raisins in the 24-ounces box, thus the ratio is of $\frac{60}{24} = 2.5$ , that is, 2.5 raisins per ounce.
For brand B, there are 18 raisins in the 6-ounce box, 36 in the 12-ounce, and it follows this ratio, thus $\frac{36}{12} = \frac{18}{6} = 3$ , thus, 3 raisins per ounce.
For brand C, there are 20 raisins in the 10-ounce box, 30 in the 15-ounce, and so on, thus $\frac{20}{10} = \frac{30}{15} = 2$ , thus, 2 raisins per ounce.
Due to the higher computed ratio, brand B advertises the greatest ratio of raisins per ounce.
