Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.
44
The pattern is +1,+1,x2
4/5 mile in 1/2 hour.
1/2 * 2 = 1
4/5 * 2 = 8/5
8/5 miles per hour or 1.6 miles per hour
The answer to the question is y=-4x+23
