Best Answer

The perimeter of a rectangle is equal to 2 x length + 2 x width.

(2 x 24 cm) + (2 x 10 cm) = 48 cm + 20 cm = 68 cm

How do you find the perimeter of a rectangle when only the area is given?

You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.
