Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.

From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.

A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in

Answer: D. 252 inches squared, last choice

Answer:

Median is 18.

Mean is 22.

Step-by-step explanation:

Median has to be ordered from least to greatest:

1, 9, 17, 18, 25, 41, 43

then the median is the number in the middle, which is 18.

Mean is the sum of all the numbers, divided by 7 (because there are 7 numbers given)

25+18+9+1+43+17+41= 154

154/7 = 22

In the figure to the right, AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm. Find the perimeter of the figu

Answer:

Step-by-step explanation:

<u>The Perimeter of Plane Shapes</u>

If we are given a plane shape, the perimeter is the measurement of the boundary of it. In case the shape is made of lines, the perimeter is the sum of the lengths of all of them.

We are given an irregular shape, we only need to add all the sides. But we don't have all the individual sides. Let's write the expression for the perimeter.

P=AE+ED+DC+CB+BA

We have: AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm. Note we don't have AE or DC, but we have their sum, so

P=AE+DC+ED+CB+BA

Recall that AB=BA, the order of the letters is not important. The perimeter is

$\displaystyle P=1\frac{1}{5}+1\frac{1}{4}+1\frac{3}{10}+1\frac{3}{4}$
