a school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long. Which patio has a greater area?

Answers

Answer:

The 21' by 21' square patio is larger by 9 square feet

Step-by-step explanation:

[tex]24 \times 18 = 432[/tex]

[tex] {21}^{2} = 441[/tex]

The square patio will have more area than the rectangular one.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that the school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long.

The area of the rectangle is calculated as,

Area = L x W

Area = 24 x 18

Area = 432 square feet

The area of the square is calculated as,

Area = S²

Area = (21)²

Area = 441 square feet

The area of the square is greater than the area of the rectangle.

2+3/4x=5/12
Rewrite the equation so that it does not have any fractions

Answers

Answer:

24+9x=5

Step-by-step explanation:

First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.

2*12=24,

3/4*12=36/4=9,

5/12*12=60/12=5.

Using these values will give your final equation: 24+9x=5

Answer:
24+9x=5

Explanation:
To remove the fractional values, we need to multiply both sides of the equation by their denominators so they get canceled out.

2+3/4x=5/12
1) Multiply both sides of the equation by 4 since it is the denominator of 3/4
8+3x=20/12
2) Simplify the fraction 20/12
8+3x=5/3
3) Multiply both sides of the equation by 3 since it is the denominator of 5/3
24+9x=5
