The perimeter will be tripled.
21 x 2 has greatest perimeter
Without knowing the dimensions it is not possible to say.
834.84 feet
If they are the dimensions of a rectangle then the perimeter is: 2*(26+16) = 84
To know the perimeter, you must know the dimensions (length and width). But there are many possible dimensions if you have 24 square feet.
area 63 and perimeter is 32
The perimeter will be tripled.
21 x 2 has greatest perimeter
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
what are the dimensions of the rectangle with this perimeter and an area of 8000 square meters
Without knowing the dimensions it is not possible to say.
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
834.84 feet
If they are the dimensions of a rectangle then the perimeter is: 2*(26+16) = 84
Area is quadrupled (*4) and perimeter is doubled.
When all of the linear dimensions are doubled . . .-- the perimeter is also doubled-- the area is multiplied by 22 = 4.
