Answer: 48 units
Step-by-step explanation:
In a rhombus, all the sides are equal. This is shown by equality sign on each side of the given rhombus. Therefore,
LM = MN
3x - 3 = x + 7
Subtracting x from the left hand side and the right hand side of the equation, it becomes
3x - x - 3 = x - x + 7
2x - 3 = 7
Adding 3 to the left hand side and the right hand side of the equation, it becomes
2x - 3 + 3 = 7 + 3
2x = 10
x = 10/2 = 5
Therefore, the length of each side is
3 × 5 - 3
= 15 - 3 = 12
Therefore, the perimeter of the rhombus is
12 × 4 = 48 units
Answer:
Step-by-step explanation:
Total Surface Area of Cylinder = 
Note: Do not get tricked by the 24cm (taking 24cm as the radius), that is the diameter.
To find r, radius = 
=
= 12cm
Now we know r = 12cm, h = 18cm
Now we substitute r and h into the formula to find the total surface area.
Total Surface Area of Cylinder = 
You could group the numbers with the common denominator and that is 3 1/2 and 4 1/2. So you could make it (4 1/2 + 3 1/2) + 2
