Given colon space Permiter space of space both space the space plots space have space same space perimeter.
rightwards double arrow Perimeter space of space straight a space Reactanle space equals space Perimeter space of space straight a space Square
rightwards double arrow 2 straight l space plus space 2 straight b space space space equals space 4 space cross times space side
rightwards double arrow 2 space cross times space 70 space plus space 2 straight b space space equals space 4 space cross times space 64
rightwards double arrow straight b space equals space 58 straight m space
rightwards double arrow Area space of space straight a space rectangle space equals space straight l space cross times space straight b space equals space 70 space cross times space 58 space equals space 4060 straight m squared
rightwards double arrow Area space of space straight a space Square space minus Area space of space straight a space rectangle space space equals space 4096 space minus space 4060 space equals space 36
Here space area space of space straight a space Square space plot space is space greater space by space 36 straight m squared.
