essie is helping her grandmother plant a garden in the shape of the trapezoid shown. ​ ​ ​ The garden will have the following dimensions: • base one is feet long • base two is times the length of base one • height is feet What is the area, in square feet, of this garden?

the bottom of the spinner is not flat.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

2/3
