For their homecoming parade, the students of U-Math have created a colorful banner, 51 meters in length, that is made of two pieces of parachute material. The short piece is 21 meters shorter than the longer piece. Find the length of each piece.

Length of long piece= 36 m

Length of the short piece= m

15 meters

Step-by-step explanation:

The piece is made out of two pieces of parachute, a short one and a long one. The short on is 21 meters shorter than the longer one, if the longer one is 36 meters than the short piece is 36 meters - 21 meters

36 - 21 = 15

This means that the short piece is 15 meters long

We can check this by adding the short piece and the long piece hoping that it equals the total length, 51 meters

36 + 15 = 51

That means that you were correct

its the fourth option
