Why I can’t see the answer

Iam a rectangle. my perimeter is 60 feet. how much are do i cover?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

X2 + y 2 = 36 x + y = 6 solve the system of equations.
