Let the length of square be l(length)
Perimeter of square = 4l
48cm= 4l
48/4= l
12=l
This,l=12 cm
50.24
Circumference = pi*d
P=3.14 d=16
Is there a picture or something?
Answer: (-5,4)
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
