It is 5 feet because 2*(10+5) = 30 feet which is the perimeter
Well, if you're talking about a square, then the perimeter is twice the length plus twice the width; in this case it would be 30 feet...
60ft
It is: 30*30 = 900 square inches
10 feet because 10+5+10+5 = 30 feet
The perimeter is 30 feet for this rectangle.
It is 5 feet because 2*(10+5) = 30 feet which is the perimeter
It depends on the shape of your room. If your room is a rectangle then your perimeter is 102 feet.
30 * pi ≈ 94
20 feet
Well, if you're talking about a square, then the perimeter is twice the length plus twice the width; in this case it would be 30 feet...
20
Type your answer here... Perimeter = 25+25+30+30 = 110 feet
30
They can, but not necessarily. Let's say we have a rectangle of 5x6 and another of 1x30. The areas of both are 30 square feet, but their perimeters are different. Perimeter of 5x6: 5+5+6+6=22 feet Perimeter of 1x30: 1+1+30+30=62 feet There are many more examples of this.
270 feet.
0.5*apothegm*perimeter = 0.5*3*20 = 30 sq feet
