The length of the shortest piece is 5cm.
Given that the length of the board = 62cm
Let the length of the first piece be x cm.
Hence, according to the question,
Length of the second piece = 2x cm
Length of the third piece = (2x + 7) cm
We have to find the length of the shortest piece.
Hence, we can write,
62 = x + 2x + (2x + 7)
62 = 5x + 7
5x = 62 - 7 =55
x = 55/11 = 5 cm
Hence, the shortest side is the first side of 5 cm.

If we make
an integer that represents the adults that bought tickets, and
the number of students, then we have the equations
, and
.
Using the second equation, we find that
, so we plug this value of
into the first equation to get
. We simplify to find
. We divide by
to isolate the desired variable to get
.
Answer:
The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=1/2bh where b is the base and h is the height of the triangle.
Step-by-step explanation:
The point is that when you convert, you may get a fractional number, so you need to round up to the next can.
