Okay. So as you probably know, area is l * w. 10 * 5 is 50, so the original area is 50 square feet. With each side being increased equally, after that is done, the area is 84 square feet. If you know basic multiplication, 12 * 7 is 84. 12 - 10 is 2. 7 - 5 is 2. That number being added is the same for all sides. The amount added to each side is 2 feet.

What is the solution to w-11=1.3
trapecia [35]
<span>Simplifying w + -11 = 1.3
 
Reorder the terms: -11 + w = 1.3
 
Solving -11 + w = 1.3
 
Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + w = 1.3 + 11
 
Combine like terms: -11 + 11 = 0 0 + w = 1.3 + 11 w = 1.3 + 11
 
Combine like terms: 1.3 + 11 = 12.3 w = 12.3
 
Simplifying w = 12.3 <--- (Answer)
