Step-by-step explanation:Hey there!The length is 40 cm more than breadth.Sp let the breadth be x.So, length will be 40+xNow, we know that Perimeter of a rectangle is 2(Length+Breadth)We can write that 380 cm = 2(40+x+x)190 = 40+2x2x = 150x = 75 cm.So, breadth is 75 cm.And length is 75+40 = 115 cm.Hope it helps:)
