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)
subtracting both sides from 20:
Dividing both sides by 2:
Length is 26 feet.
And, to get the area we put the formula of finding the area:
Therefore, the area of the rectangular playroom is 260 feet² .
