Find the value of x
x+9.8=14.7
x=4.9
Then plug it in the second equation
8(4.9-3.7)
8(1.2)
9.6
Hope this helps.
Area = 2831.25 square yards
Perimeter =215.6 yards
EXPLANATION
The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.
That means, area of the rectangular field is given by the formula,

We just have to substitute

and

into the given formula and evaluate.
This implies that;

This gives the area of the rectangular-shaped field to be;

square yards.
Now for the perimeter, we use the formula

Or

Substituting the values for the length and width gives,



Hence the perimeter of the rectangular shaped field is 215.6 yards.
B if you need an explanation just comment
Since 36x² + 60x + 25 is the perfect square trinomial, we use this formula a² + 2ab + b² = (a + b)². Hence, the solution is (6x + 5)²
Answer:
It took Pedro <em>3.81 hours</em> to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = 
Formula for distance can be seen as:

Distance traveled by Mike = 
Rate of Pedro while hiking the same distance = 
Given that, Pedro also travels the same distance.
And we have to find the Time.


It took Pedro <em>3.81 hours</em> to reach the lake.
