Answer:

A = 400 cm^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s where s is the side length

80 = 4s

Divide each side by 4

80/4 = 4s/4

20 =s

We want to find the area of the square

A = s^2

A = 20^2

A = 400 cm^2

The distance traveled by Raven in 1 hour at the given rate is 4.0 miles.

The given parameters:

Distance traveled by Raven = 2 2/5 miles
Time of motion, t = 3/5 hour

The speed of Raven motion is calculated as follows;

$V = \frac{Distance}{Time} \\\\V = Distance\ \times \ \frac{1}{Time} \\\\V = 2\frac{2}{5} \ miles \ \ \times \ \ \frac{1}{3/5 \ hr} \\\\V = \frac{12}{5} \ miles \ \ \times \ \ \frac{5}{3 hr} \\\\V = 4 \ mph$

The distance traveled by Raven in 1 hour at the given rate is calculated as follows;

$D = 4 \times 1\\\\D = 4 \ miles$
