Question

Area of rectangle and the square is 144cm each what is the difference between perimeter of rectangle and square if the lengh of rectangle is 4cm more than the side of square

Answer 1

Answer:

Step-by-step explanation:

Let x=side of square

are x²=144

x=12 cm

perimeter of square=4x=4*12=48 cm

Now one side of rectangle is 4cm more than the side of square

so one side=12+4=16 cm

other side=area/side=144/16=9 cm

So perimeter=2(16+9)=2*25=50 m

difference in perimeter=50-48=2 cm
