2 left parenthesis 3 straight x plus straight x right parenthesis equals 192... left parenthesis Since space 2 left parenthesis straight l plus straight b right parenthesis equals straight P right parenthesis
rightwards double arrow 2 left parenthesis 4 straight x right parenthesis equals 192
rightwards double arrow 8 straight x equals 192
rightwards double arrow straight x equals 24
Hence comma space breadth space of space the space rectangle equals 24 space straight m
and space length equals 24 cross times 3 equals 72 space straight m end style
