Answer» Perimeter = 15 3/7 units (Given) Length = 4 2/7 (Given) Find the BREADTH: Perimeter = 2 ( Length + Breadth) Substitute Perimeter = 15 3/7 and Length = 4 2/7 : 15 3/7 = 2 (4 2/7 + Breadth) 108/7 = 2( 30/7 + Breadth) Distribute 2: 108/7 = 60/7 + 2Breadth Subtract 60/7 from both SIDES: 2Breadth = 108/7 - 60/7 2Breadth = 48/7 Divide both sides by 2: Breadth = 48/7 ÷ 2 Breadth = 24/7 Change to improper fraction: Breadth = 3 3/7 units Answer: Breadth = 3 3/7 units |
