A square patio has an area of 136 square feet. How long is each side of the patio to the nearest tenth?

11.7 feet

Step-by-step explanation:

Area finds the length times the width (LxW). In other words, area is how long the first side is multiplied by how wide the second side is. If A=LxW, and we know A is 136, then we know that 136=LxW. This alone isn't enough to find L and W. However, we do know that the patio is a square. Squares have equal sides, so L and W will be the same number. Basically, you need to find the number that equals 136 when it's multiplied by itself. X multiplied by X needs to be 136. You can do this easily with a calculator, if you're allowed to have one. just use the square root function on 136, and be sure to round your answer. If you're not allowed to use a calculator, it's a bit more trial-and-error. Try to see what numbers multiplied by themselves get close to 136, and narrow it down from there (ex. if 11 is too little and 12 is too much, the answer is between 11 and 12). You can also look up video tutorials for how to find a square root without a calculator, or use other study platforms. I hope this helps, and feel free to ask me any questions!! :)

it would open into a square depending on the type of envelope i’m not sure about the second part

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
