Answer:
56
Step-by-step explanation:
The triangular prism has 5 sides. We will find the area of each individual side and add them together.
Sides 1 and 2: The triangles
These triangles have base 6 and height 4. Use the area of a triangle formula A=1/2*base*height=1/2*6*4 = 12 to get the area of each one.
Sides 3 and 4: The rectangular sides other than the base
These are rectangles with length 5 and width 2. A = 10.
Side 5: The base
This is a rectangle of length 6 and width 2. A = 12.
Adding it all up:
12+12+10+10+12 = 56.

The area of the figure is 1,000 square feet
Step-by-step explanation:
we know that
The area of the kite ABCD
is equal to
![A=\frac{1}{2}[AC*BD]](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5BAC%2ABD%5D)
where
AC and BD are the diagonals of the kite
we have
substitute
![A=\frac{1}{2}[40*50]=1,000\ ft^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B40%2A50%5D%3D1%2C000%5C%20ft%5E2)
Heather is about 167.5 cm
5’7” is equal to 67 inches
when you multiply 67 inches by 2.5 cm (which is around 1 inch) you get 167.5cm
1546/12 = 128.3333333333333333333333333333333333333

Step-by-step explanation:
Answer:
Step-by-step explanation:
formula: a^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 30 = 289
-30 -30
a^2 = 259
(square root)
a = approximately 16
