Answer:
SA = 52 square meters
Step-by-step explanation:
<em>First, the equation I'll be using for this problem is</em><em> SA=2(wl+hl+hw)</em><em>! Our </em><em>width is 4m, </em><em>our </em><em>length is 3m</em><em>, and our </em><em>height is 2m</em><em>. To begin to solve this problem we are going to input these values in to the equation above.</em>
SA = 2(4 × 3 + 2 × 3 + 2 × 4)
<em>Next, we are going to multiply our values inside the parenthesis based on the </em><em>PEMDAS</em><em> </em><em>strategy</em><em> (if you have any questions about this, feel free to ask below :).</em>
SA = 2(12 + 6 + 8)
<em>Now, we can add our values inside the parenthesis.</em>
SA = 2(26)
<em>Finally, all we have to do is distribute the 2 outside of the parenthesis to inside the parenthesis.</em>
SA = 52 square meters

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
<h2>Answer: A trapezoid with bases of 6 mm and 14 mm and a height of 8 mm </h2>
The parallelogram in the figure has an area of 
, according to the following formula, which works for all rectangles and parallelograms:
(1)
Where 
is the base and 
is the height
The<u> area of a triangle</u> is given by the following formula:
(2)
So, for option A:
Now, the <u>area of a trapezoid </u>is:
(3)
For option B:
For option C:
>>>>This is the correct option!
For option D:
<h2>Therefore the correct option is C</h2>
Since they completed 2/15 miles in 20 mins.
There are 60 mins in an hour so we can multiply they amount of work they did by 3 and that will equal .4
