Perimeter = 2L + 2W where L = length and W = width.
So we have
2*14.14 + 2W = 59.59
2W = 59.59 - 2*14.14
2W = 59.59 - 28.28 = 31.31
W = 31.31 / 2 = 15.66 to 2 decimal places
(-2,4) hope this helps if it’s it’s reflected over the x-axis that means the what ever ordered pair it is it is the opposite like for example (-3,5) it would be (3,5) because it saying reflect over the x-axis you only change the first number hope this really help you
766% ;) just use a calculator then you will find it
