The perimeter of one of the rectangular playrooms at Miss Pittypat's Day Care is 72 feet. It's width is 10 feet.

Alex17521 [72]

Answer:

The area of the rectangular playroom is 260 feet² .

Step-by-step explanation:

Given:

The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.

Now, to find its area we need the length .

So, putting the formula of perimeter we get it's length:

Let the length be l .

Perimeter = 2( length + width)

$72=2(l+10)$

$72=2l+20$

subtracting both sides from 20:

$72-20=2l+20-20$

$52=2l$

Dividing both sides by 2:

$52\div2=2l\div2$

$26=l$

Length is 26 feet.

And, to get the area we put the formula of finding the area:

$Area=length\times width$

$Area=26\times 10$

$Area=260$

Therefore, the area of the rectangular playroom is 260 feet² .

The ratio of the corresponding side lengths of two similar posters is 7 in:20 in. What is the ratio of the perimeters?

gregori [183]

The ratio of their perimeters is still 7:20. The poster is a rectangle shape. If the length of each side of a poster is proportional to the other by a certain ratio, the sum of the lengths of all sides is also proportional by the same ratio. You can suppose the lengths of four sides of poster A are 7a, 7b, 7c, 7d, so poster B has 20a, 20b, 20c, 20d. (7a+7b+7c+7d)/(20a+20b+20c+20d)=7(a+b+c+d)/20(a+b+c+d)=7/20.

What is 4x^2-1/ (x+4) (2x-1) simplified

Nadusha1986 [10]

Answer:

:)

Step-by-step explanation:

$\frac{4x^2 - 1}{(x+4)(2x-1)} = \frac{(2x)^2 - (1)^2}{(x+4)(2x-1)}$

$=\frac{(2x-1)(2x+1)}{(x+4)(2x-1)}\\\\=\frac{2x+1}{x+4}$
