Answer:

153.5ft²

Step-by-step explanation:

You need to break it down into parts. I'm starting with the triangle at the top. We know that its height is 3ft, and part of its base is 3. Look down at the bottom, and you will see that two of the steps, the four feet and the 2 feet ones, add up to align directly with the base, so the base is 3+4+2=9. The area of a triangle is 1/2(base)(height), so 1/2(9)(3)=13.5ft². Then I'm going to do the rectangle on the far left. Length of 6ft, width of 9ft, a rectangle's area is found by (length)(width), so 6*9 = 54ft². Now all that's left is the area under the triangle, which can be split into two rectangles, one with an area 15*4 = 60ft² and the other with (15-2)*2 = 26ft². Now you add all of these up:

13.5ft²+ 54ft²+ 60ft²+ 26ft²= 153.5ft².

Triangle:

A = 3 x 9 x 1/2 = 13.5

Large rectangle (center):

A = 9 x 12 = 108

Medium rectangle:

A = 4 x 6 = 24

Small rectangle (bottom):

A = 4 x 2 = 8

Figure:

A = 13.5 + 108 + 24 + 8 = 153.5 square feet

Hope this helps! :)

You use pythagorean theorem so 30 is legA and 10 is legB so 20^2+10^2= square root legC which is 31.62

Karolina [17]

The given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2.3 raised to the fifth power divided by 0.9 raised to the fourth power, all raised to the third power.

Write the expression in the mathematical form and solve:-

[ ( 2.9⁵) / ( 0.9 )⁴ ]³ = [ ( 2.9⁵) / ( 0.9 )⁴ ]³

                             =  [ ( 2.9 )¹⁵ / 0.9 )¹² ]

Therefore, the given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.
