I need help with this please. I don't understand how to do this

(If it's asking for Area of the composite figure) A=16 ft²

Step-by-step explanation:

1. Split the shape into a square and a rectangle (this is just how I split it, you don't have to split it like this)

2. Find the area of the square and rectangle

Square: 2 x 2 = 4 square ft

Rectangle: 6 x 2 = 12 square feet

3. Find total area by adding the area of the square and rectangle

A= 4 + 12 = 16 square ft

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
