Plz help Find the perimeter and the area of the following rectangle.

A=21 units squared; P=20 units

Step-by-step explanation:

The width of the rectangle is 3 units (5-2=3)

The length of the rectangle is 7 units (12-5=7)

A=l*w

A=7*3

A=21 units squared

P=2(l+w)

P=2(7+3)

P=2(10)

P=20 units

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.
