The perimeter formula for a rectangle is 2l + 2w, where l is the length and w is the width.

Correct.

Step-by-step explanation:

This is the perimeter formula for a rectangle.

Perimeter is l + l + w + 2

p = 2l + 2w

question is incomplete.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
