Answer:

131.25 in ^2

Step-by-step explanation:

Find the area of the rectangle on the left

A = l*w

A = 11.75 * 6 = 70.5 in ^2

Now find the area of the rectangle on the right

The length is 9 and  the height is 11.75 - 5 = 6.75

A = 9 * 6.75

A = 60.75 in ^2

Add the areas together

70.5+60.75 = 131.25 in ^2

Answer:131.25

Step-by-step explanation:

11 3/4 x 6 = 70.5 (area of first rectangle)

11 3/4 - 5 = 6.75 (to find the height of the other figure)

6.75 x 9 = 60.75 (area of 2 figure)

60.75 + 70.5 = 131.25

a rectangular pyramid has a volume of 190 cubic centimeters. Find two possible sets of measurements for the base area and height
DerKrebs [107]
<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>

<em><u>Solution:</u></em>

<em><u>The volume of rectangular pyramid is given as:</u></em>

Volume = \frac{1}{3} \times base\ area \times height

Given that,

<em><u>Rectangular pyramid has a volume of 190 cubic centimeters</u></em>

<em><u></u></em>190= \frac{1}{3} \times base\ area \times height<em><u></u></em>

<em><u>Substitute, base area = 570 and height = 1</u></em>

Then we get,

190 = \frac{1}{3} \times 570 \times 1\\\\190 = 190

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively

<em><u>Substitute, base area = 285 and height = 2</u></em>

190 = \frac{1}{3} \times 285 \times 2\\\\190 = \frac{1}{3} \times 570\\\\190 = 190

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively
