If the length of each side of a triangle is cut to 1/3 of its original size, what happens to the area of the triangle?
Blababa [14]

Answer:

The new area of the triangle is (1 / 9) th of the original area.

That is to say the original area of the triangle is decreased to (1/9) th of its value.

Step-by-step explanation:

The area of a triangle is given by, Area = 1/2 \times base  \times  height

If each side of a triangle is cut to 1/3 of its original size then the base will also become one third and the height will also become one third.

Therefore the new area  will be given by  = 1/2  \times (1/3 \times base)  \times  (1/3  \times height)

   = 1/9  \times 1/2  \times base  \times height

   = 1/9  \times Area.

The new area of the triangle is 1 / 9 th of the original area.

Task: Volume &amp; Surface Area
Triss [41]
Okay so starting off I get that this math can be really confusing but you’ll get it if you keep working at it. Don’t give up you got this. For part it it is asking for the volume in cubic feet to do this you multiple H•W•L

H=hight

W=Width

L=Length

Now you don’t really need to know exactly which side is the H,L, or W but since you only have 3 sides with domentions you know that you multiply all three sides now it doesn’t matter what order you do it in.

Please respond if this helped for part A. You got this keep your head up.

harina [27]

Answer:

7:\dfrac{1}{3}=21 pieces

Step-by-step explanation:

Suppose you have a 7 feet long wood.

You need to find how many \frac{1}{3}-foot pieces can be cut from this wood.

To find this number of pieces, you have to divide the whole length of the wood by the length of one piece:

7:\dfrac{1}{3}=\dfrac{7}{1}\cdot \dfrac{3}{1}=21
