Answer:
C
Step-by-step explanation:
Let length of rectangle be "l"
Let width of rectangle be "w"
We know,
LENGTH is 2 MORE THAN WIDTH, we can write:
l = w + 2
Also, note the perimeter is the sum of all 4 sides of a rectangle, thus:
length + width + length + width
Now,
The perimeter is given as 72, so we can write:
l + l + w + w = 72
2l + 2w = 72
We have 2 equations that we need to solve and find the length (l).
The first equation is:
l = w + 2
Rearranging, we have:
w = l - 2
We put this into 2nd equation and find the value of l:

The length is 19 meters, the correct answer is C
Answer:
15.59 square inches
Step-by-step explanation:
In the required given diagram, the slant height of the cone was given as 3.6 inches.
The least amount of paper required would be equal to the curved surface area of the cone.
curved surface area of a cone =
rl
where r is the radius and l the slant height.
circumference of the top rim = 8.66 inches
circumference = 2
r
⇒ 8.66 = 2
r
4.33 =
r
r = 4.33/
curved surface area =
x 4.33/
x 3.6
= 4.33 x 3.6
= 15.588 square inches
Thus, the least amount of paper that can form the cone shaped cup is 15.59 square inches.
