Question

The perimeter of a rectangle is 354 km. Its side lengths are 81 km, 81 km, and 96 km. The fourth side length is given as "f" km. What is the value of f?​

Answer 1

The fourth side = f, now let's solve for f

• f + 81 + 81 + 96 = 354

• f + 258 = 354

• f = 354 - 258

• f = 96

value of fourth side = f = 96 km
