Perimeter of rectangle =2(l+b)
let length be 7x and breadth be 4x
2(7x+4x)=88
x=4
Therefore length =28cm and breadth be 16cm
Area of rectangle =lb (i.e) 28*16=448cm sq
Area of square + Area of rectangle =644(given in question)
l*l +448=644
So l=14
Perimeter of square=4l
4*14=56cm

So your answer is option E(56cm)
