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 .

What value of z makes the equation z+6÷13=4 true?
netineya [11]

Answer:

z = 46/13

Step-by-step explanation:

Step 1: Write equation

z + 6 ÷ 13 = 4

Step 2: Solve for <em>z</em>

  1. Rewrite: z + 6/13 = 4
  2. Subtract 6/13 on both sides; z = 46/13

Step 3: Check

<em>Plug in z to verify it's a solution.</em>

46/13 + 6/13 = 4

52/13 = 4

4 = 4
