Options: Parallelogram, Triangle, Trapezoid

9 x 7 = 63 < Parallelogram

10 x 6.8 = 68, 68 divided by 2 = 34 < Triangle

13 + 15 = 28, 28 x 6 = 168, 168 divided by 2 = 84 < Trapezoid

The trapezoid has the greatest area.

Formula of trapezoid:

B1(base 1) + B2(base 2) x H (height) x 1/2 (basically dividing by 2)

Formula of triangle:

B(base) x H(height) x 1/2 (basically dividing by 2)

Formula of Parallelogram:

B(base) x H(height)

false

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
