Find the length of the two adjacent sides of the pallelogram.

Question

The length of one side of a parallelogram is 3 more than twice the length of the adjacent sides. The perimeter of the parallelogram is 30cm. Find the lengths of the two adjacent sides of the parallelogram.

Answer 1

adjacent sides can be x and 2x+3, and this will account for exactly half of the perimeter, 30 cm.

 

so you have this equation to solve: 2x+3 + x = 15.
