Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = 
8 = 
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = 
x = 
x = 
x = 
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.

Approximate dimensions:



Step-by-step explanation:
Let's assume width of rectangle is w ft
The length of a rectangular flower bed is 2ft longer than the width
so,
length =w+2

now, we can find area

now, we can plug it


we are given area =6
so, we can set it equal
and then we can solve for w


we can use quadratic formula


now, we can compare and find a,b and c
a=1 , b=2 , c=-6


we know that dimension can never be negative
so, we will only consider positive value
