Answer:
A
Step-by-step explanation:
If the figure is to be a parallelogram, opposite sides must be the same length. This requires ...
15 = x +8 ⇒ x = 7 . . . . long sides equal length
and ...
x +2 = 2x -5 . . . . . short sides equal length
7 = x . . . . . . . . . . add 5-x
The value x=7 will make opposite long sides have lengths 15 mm and opposite short sides have lengths 9 mm.
Figure WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.
solution given:
For Cuboid
length[l]=11mm
breadth [b]=9mm
height[h]=6mm
For semi cylinder
height[H]=11mm
radius[r]=
Now
Totalsurface area=2(lb+bh+lh)+½(2πr(r+H))-l*b[/tex]
:2(11*9+9*6+11*6)+22/7*4.5(4.5+11)-11*9
:438+219.2-99
:558.2mm²
Here area of base is subtracted as it is not included.

<h3>What are word problems?</h3>
- Word problems are mathematical problems expressed completely in words.
- The given problem is the rate of work done kind of word problem.
- To solve a word problem, first, observe the data given in words and apply the basic algebraic operations.
- The basic algebraic operations are addition, subtraction, multiplication, and division.
<h3>How long will 3 such machines take to pack 5000 articles?</h3>
It is given that,
A machine can pack 5000 articles in 24 hours. I.e,
1 machine → 5000 articles → 24 hours
3 machines → 5000 articles → 24/3 hours
Thus, 3 of such machines can pack the same number of articles in
24 ÷ 3 = 8 hours.
Therefore, 3 of such machines take 8 hours to pack 5000 articles.
