Which statement is true
Before the division, the area of both squares is:
After the division:
The area of the triangle is:
Substitute Area for l * w
This equals half the area of the square
The area of the rectangle is:
The length of the rectangle is now half the length of the original square.
So, we have:
Substitute Area for l * w
<em>From the values of A1 and A2, we can conclude that (a) is true</em>
Nicole used only a fraction of her ribbon to wrap the present
the length of ribbon she used is 6 feeet
so lets name the length of the ribbon she had originally as X
the fraction of X she used was - 3/8 of X
so we can write the following equation
when of function is used we multiply
3X = 6*8
3X = 48
X = 16
therefore length of the original ribbon piece Nicole had was 16 feet
