Answer:

24ft²

Step-by-step explanation:

divide up the shape:

big triangle:

(looking for base)

9.8²= 4² + b²

b = 8.95ft

(finding area)

0.5*8.95*4 = 17.9ft²

small triangle:

(looking for base)

12-8.95=3.05ft

(finding area)

0.5*3.05*4 = 6.1ft²

Whole Shape:

17.9+6.1 = 24ft²

Look at the picture.

The triangle ADC and the triangle CDB are similar.

Therefore corresponding sides are all in the same proportion:

$\dfrac{y}{4}=\dfrac{12}{y}\ \ \ \ |cross\ multiply\\\\y^2=48\to y=\sqrt{48}\\\\y=\sqrt{16\cdot3}\\\\y=\sqrt{16}\cdot\sqrt3\\\\y=4\sqrt3$

Y - 2 = -4/3 ( x + 6)

Vikentia [17]

Y-2=-4/3(x+6)
y-2=-4/3x-24/3
y=-4/3x-24/3+2
y=-4/3x-24/3+6/3
y=-4/3x-18/3
y=-4/3x-6
