The height of the triangle is 8 centimeters.

The area of the rectangle is 48 square centimeters.

The area of the rectangle is 216 square centimeters.

The area of the irregular figure is 264 square centimeters.

Step-by-step explanation:

The height of the triangle is the total height of the figure minus the height of the rectangle, that is:

$h = 26\,cm - 18\,cm$

$h = 8\,cm$

The height of the triangle is 8 centimeters.

The area of the triangle (), measured in square centimeters, is determined by the following formula:

$A = \frac{1}{2}\cdot b\cdot h$ (1)

Where:

- Base of the triangle, measured in centimeters.

- Height of the triangle, measured in centimeters.

If we know that $b = 12\,cm$ and $h = 8\,cm$ , then the area of the triangle is:

$A = \frac{1}{2}\cdot (12\,cm)\cdot (8\,cm)$

$A = 48\,cm^{2}$

The area of the rectangle is 48 square centimeters.

The area of the rectangle (), measured in square centimeters, is determined by the following formula:

$A = b\cdot H$ (2)

Where is the height of the rectangle, measured in centimeters.

If we know that $b = 12\,cm$ and $H = 18\,cm$ , then the area of the rectangle is:

$A = (12\,cm)\cdot (18\,cm)$

$A = 216\,cm^{2}$

The area of the rectangle is 216 square centimeters.

The area of the irregular figure is the sum of the areas of the rectangle and the triangle. Then, the area of the irregular figure is 264 square centimeters.

Answer from: Quest

answer set (b) 0.5, 3/4 80% is in order from least to greatest.

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form. typically, the best form in which to evaluate rational numbers is in decimals. in order to convert a percent to a decimal, you would divide the given percentage by 100. you can also accomplish the conversion by moving the decimal point over two places to the left. for example, the decimal value of 80% is 80/100, or 0.8. in order to convert a fraction to a decimal, you need to divide the numerator by the denominator. for example, 3/4 is 0.75. so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
