One side of the quadrangle is 48cm, the second side is 14cm larger than the first, and the third side is 2 times

One side of the quadrangle is 48cm, the second side is 14cm larger than the first, and the third side is 2 times less than the sum of the first two sides. Find the fourth side if the perimeter of the quadrangle is 200m.

By the first action, we find the second side of the quadrangle: 48 + 14 = 62 (see);

By the second action, we find the sum of the first two sides of the quadrangle: 48 + 62 = 110 (see);

By the third action, we find the third side of the quadrangle: 110/2 = 55 (see);

The perimeter of a quadrilateral is the sum of the lengths of all its sides.

Since the perimeter is known, we can write the following equation:

x + 48 + 62 + 55 = 200;

x + 110 + 55 = 200;

x + 165 = 200;

x = 200 – 165;

x = 35.

35 (see) is the length of the fourth side of h.
