Answer:
22 1/4 feet
Step-by-step explanation:
you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).
use Pythagorean Theorem to find the base side, which represents the distance between the posts
a² + 9² = 24²
a² + 81 = 576
a² = 576 - 81
a² = 495
a =
a = ·
= 3
, which is approx 22.25
Answer: 4.2 yards
Step-by-step explanation:
Let x = length of the Flores' lawn in yards.
Then, Area of lawn = 4x sq. yard [Area of rectangle = width x length , here width = 4 yds (given)]
Charge per square yard = $1.25
Charge for Flores lawn = 1.25 × (Area of lawn)
= 1.25 (4x)
= 5x
As per given,
Hence, the length of the Flores's lawn = 4.2 yards
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
