What is the area of this figure?
ludmilkaskok [199]

Answer:

          \large\boxed{\large\boxed{42 unit^2}}

Explanation:

The figure is not a regular hexagon. It is an irregular hexagon.

Please, find attached the picture with the original question and the figure.

You can split the figure into two triangles and one rectangle.

The rectangle has dimensions: 7units × 4units, thus its area is 28 units².

Both the upper triangle and lower triangle have base 7 units and height 2 units.

Hence the area of each triangle is:

       area=(1/2)base\times height

       

      area=(1/2)7units\times 2units = 7units^2      

Hence, the area of the hexagon is:

           28units^2+7units^2+7units^2=42units^2

Suppose you are standing such that a 32-foot tree is directly between you and the sun. If you are standing 140 feet away from th
Ghella [55]

Answer:

Height = 4 feet

Step-by-step explanation:

To determine how tall I can be we take the difference between the shadow cast by the 32-feet tree and the distance away from the tree

But the tree is 32 feet tall but on shadow it's 160

So lemme determine how long I'll be in my shadow first

Distance away from tree= 140 feet

Length of shadow cast by tree

= 160 feet

Length of shadow= 160-140

Length if shadow= 20 feet

My height= x

X/20= 32/160

X= 20*32/260

X = 4 feet

Height = 4 feet
