plug : pi · 5^2 · 22 into a calculator and that is the answer
Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
Original length: x
original width; x-3
original area: x(x-3)
when the dimensions doubles, that is, increase by a factor of 2, the area increase by 2²
4[x(x-3)]
4x(x-3)=4x²-12x
you can also do it this way:
original length: x doubled: 2x
original width; x-3 doubled: 2(x-3)
new area: 2x[2(x-3)]= 4x²-12x
