A parallelogram has opposite and congruent sides

  • <em>5 units is a reasonable estimate of the parallelogram's height</em>
  • <em>The area of the parallelogram is 50 square units</em>

Given that:

Base = 10

<u>The height of the parallelogram</u>

The attached diagram does not show the full picture of the parallelogram; however the parallelogram's height is independent of its base.

So, we can conclude that 5 units is a reasonable estimate

<u>The area</u>

The area of a parallelogram is:

Area = Base \times Height

So, we have:

Area = 10 \times 5

Area = 50

Hence, the area of the parallelogram is 50 square units.

Can someone help me to find length CD
uysha [10]

Answer:

CD = 3.602019190339

Step-by-step explanation:

CD = DA - CA

DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507

BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278

CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168

Then

CD = 16.355388523507 - 12.753369333168 = 3.602019190339

First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
