Let the length of the base be x.

Height = 3x

Area = 27

$\frac{1}{2} bh$ = 27

$\frac{1}{2} * x * 3x$ = 27

$x^{2}$ = 18

x = $\sqrt{18}$ = 4.24264068712 ≈ 4.24

Hence,

The length of the base is 4.24 ft.

Height = 3x = 3 * 4.24264068712 = 12.7279220614 ≈ 12.72

Hence,

The height is 12.72 ft

2x+3y= -1

Step-by-step explanation:

2x+3y=5

3y= -2x+5

y= -2/3x + 5/3

m= -2/3

put the points( -2,1) in this equation to get b

1= -2(-2/3)+b

b= 1-4/3

=-1/3

so the equation is

y = -2/3x -1/3

3y= - 2x-1

2x+3y= -1
