Find the perimeter of the rectangle if one of its sides is 37 cm and the other a) 6 more b) 8 cm less

1) Since one side of the rectangle is 37 cm, and the second is 6 cm larger, in order to find the length of the second side, you need to add 6 cm to the length of the first side: 37 cm + 6 cm = 43 cm.The perimeter of the rectangle is equal to the sum all sides of it. Since the opposite sides of the rectangle are equal, then P = 2 * a + 2 * b, P = 37 cm * 2 + 43 cm * 2 = 80 cm * 2 = 160 cm.

2) Since one side of the rectangle is 37 cm, and the second is 8 cm less, in order to find the length of the second side, you need to subtract 8 cm from the length of the first side: 37 cm – 8 cm = 29 cm.P = 2 * a + 2 * b, P = 37 cm * 2 + 29 cm * 2 = 66 cm * 2 = 132 cm.
