Please help, I am so confused

Answer:

\huge\boxed{25.2\  m}

Step-by-step explanation:

In order to find the length of the missing side here, we must note that these triangles are similar.

Therefore their lengths are proportionate to each other.

So,

\frac{27.6}{11.5} = \frac{x}{10.5}

We can solve for x by cross multiplying.

10.5\cdot 27.6 = 289.8\\\\289.8 \div 11.5 = 25.2

Hope this helped!

Consider parallelogram △MNOP shown above.
Nina [5.8K]

To find the length of the sides of this parallelogram, we just have to calculate the length of each side and then proceed to find the perimeter.

The perimeter of the parallelogram is 13 units.

<h3>Perimeter of a Parallelogram</h3>

To calculate the perimeter of a parallelogram, we need the values of the length of the sides. However, if we have the details of two opposite sides, we can find the perimeter of the parallelogram because opposite sides are equal.

  • Length of MN = 2units
  • Length of MP = 4.5 units

The perimeter of MNOP can be calculated as

perimeter = 2(MP + MN)

We can substitute the values into the equation and solve

perimeter = 2(MP + MN)\\perimeter = 2 * (4.5 + 2)\\perimeter = 2 * 6.5\\perimeter = 13

The perimeter of the parallelogram is 13 units.
