If the sides of square are increased by 2 meters, the area becomes 64 square meters. find the lenght of a side of the original square

The length of a side of the original square is 6 meters long.

Step-by-step explanation:

First, you need to know that finding the area of a square means multiplying two sides together. You also need to know that a square has four equal sides, meaning that the area is a square of a number. This means that since the area of the new square is 64 square meters, then finding a side length would mean finding the square root of 64. Using a calculator, you see that the square root of 64 is eight. This means that the second square has a side length of 8 meters.

Next, the problem tells you the sides of the new square were increased by 2 meters. All you would have to do is subtract 8 by two, which equals six. That being said, the length of a side of the original square would be six meters.

+The area of the original square would be 36 meters, because 6 times 6 (side times side) equals 36.

step-by-step explanation:

if x = 2 you have to find x to finish the problem

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
