Answer:

8/9

Step-by-step explanation:

3 {}^{x}  - 3 {}^{x - 2}

3 {}^{x}  -  \frac{3 {}^{x} }{ {3}^{2} }

3 {}^{x} (1 -  \frac{1}{9} )

3 {}^{x} ( \frac{8}{9} )

So

A=8/9

The city mayor wants to use the reserved section of a rectangular park for gardening lessons conducted by the city public school
Stels [109]
You can have a lot of ways to solve this problem, but I'm going for solving for the lawn's area directly instead of solving the reserved section and subtracting it from the total area of the whole place. 

First, cut the lawn so that it becomes two shapes: a rectangle, and a triangle. Solve for both areas.

A(r) = lw
A(r) = (14)(16) 
A(r) = 224 square feet

A(t) = bh/2
A(t) = (8)(14) / 2
A(t) = 112 / 2
A(t) = 56 square feet

Add the two areas:

A(r) + A(t) = Area of lawn
224 square feet + 56 square feet = 280 square feet. 

The area of the lawn, therefores, is 280 ft^2.
