Perimeter Solve for x, if the perimeter is 45 ft. 2x 2x + 3 3x – 7 (2x + 3) + 2x + (3x – 7) = 45 7x – 4 = 45 7x = 49 x = 7

Perimeter Solve for x, if the perimeter is 34 ft. 2x – 1 2(2x – 1) + 2(x + 2) = 34 4x – 2 + 2x + 4 = 34 6x – 2 = 34 6x = 36 x = 6 x + 2

Area Solve for x, if the area is 40 ft 2. 2x (2x + 1) = 40 16x + 8 = 40 16x = 32 x = 2 8

Area Solve for x, if the area is 30 ft ft A = ½ B H ½ 12 (x – 5) = 30 6(x – 5) = 30 6x – 30 = 30 6x = 60 x = 10 x – 5
