Agiven rectangle has an area of 20 feet what is the length for various widths

The formula for finding area of a rectangle is:

To find the possibilities, list the factors of 20.

Width is the smaller side. In the numbers that were multiplied ↑, the smaller numbers are the possible widths, which is also the 3 smallest factors of 20.

Possible Widths: 1 ft, 2 ft, and 4 ft

(3x-8) or (3x+8)

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
