What is the area of the original square if a square piece of paper is folded in half vertically and the resulting figure has a perimeter of 12 cm?

16 sq cm.
Suppose the original square had sides of x cm. Then the folded rectangle has pairs of sides of length x and x/2 cm. The perimeter is 2(x + x/2) = 3x.
So 3x = 12 so that x = 4 and the area of the original square, with sides of 4 cm is 16 sq cm.

The distance around a closed plane figure?
The distance around a closed plane figure is called the perimeter. The perimeter of a figure can be calculated by adding together the lengths of each side.
The distance around a figure is called?
i am pretty sure it's perimeter but I'm not to sure Yes, it is perimeter, and if the figure is circular, it is also the circumference.
How do you find the perimeter and area of a irregular figure?
Divide the irregular figure into manageable pieces and work out their individual areas, sum the areas to that of the original figure. Measure the perimeter.
A rectangle has a perimeter of 44 the dimensions of the rectangle are scaled by a factor of 1.5 so what will be the perimeter of the resulting figure?
44 x 1.5 = 66.

What is the perimeter of the new figure who's side is increased by 2 units if the perimeter of the original 7 sided figure is 15?
29 unitsSince each side is increased by two units, and there are seven sides, then each side will be affected.The total effect will be (+2 units) x (7 sides)=+14units for the 7 sidesSince the original perimeter is 15, then15+14=29The perimeter is 29 units.
