Answer» Breadth = 75 cm÷ 100 = 3/4 mlength = area/ breadth= 54 m^2÷3/4m=72 mso , length = 72m let the required length be X.given area of the rectangle = 54cm^2width =breadth = 75cm 1m =100 cmso 75 cm = 75/100 = 0.75 marea of the rectangle = length × breadth 54 = X × 0.75X = 54/0.75X = 72 mtherefore the length of the rectangle is 72 m. 72 m is the correct answer of the given question |
