Im pretty sure its A, but dont count on me!!! i hope it helps :/
A=16 and b=63
So we have to use the Pythagoras theorem for this and that is:
a^2+ b^2 = c^2
And we want to find c , which is the long side of the triangle so..
16^2+ 63^2= 4225
So c^2 =4225
c= square root of 4225
C= 65
Answer:
The area will decrease by 9%.
Step-by-step explanation:
The area of a rectange is given by the formula below.

Let the original length and width of the rectangle be L and W respectively.
Start by finding the original area:
<u>Original </u><u>dimensions</u>
Length= L= 100%L
Width= W= 100%W
Original area= LW
Let's find the dimensions of the new rectangle in terms of L and W.
<u>New dimensions </u>
Length= (100% +30%)L= 130%L
Width= (100%-30%)W= 70%W
New area


= 91% LW
Comparing the new area with the original area:
100% LW- 91% LW= 9% LW
∴ The area will decrease by 9%.
*Note that percentage is equivalent to dividing a number by 100.
So, there is three pounds. Each bag gets a half pound. Two half pounds = one full pound. One full pound is two bags. Another pound is another two bags. And same with another. So that'd be <u><em>6 bags</em></u>, one half pound each.
