17 inches

The maximum area with straight sides and a given perimeter is a square.The sides of the square are (68/4) = 17 inches.The area is (17 x 17) = 289 square inches

parallelogram has two pairs of equivalent sides therefore it would be 17+17+30+30=94cm

Perimeter of the square: 17+17+17+17 = 68 cm

Add all three sides. Perimeter = 15 + 17 + 10 = 42

Since a square has four sides of the same length, the perimeter of the square is going to be 17 x 4 = 68 inches.

Perimeter of the square: 17+17+17+17 = 68 cm

Add all three sides. Perimeter = 15 + 17 + 10 = 42

Use Pythagoras to find the lengths of the sides: 42+12 = 17 and the square root of this is the length of the sides which works out at about 4.123105626 Perimeter: 2*4.123105626+10+12 = 30.24621125 inches

If each side of the square is 17 cm then its perimeter is 4*17 = 68 cm
