Question

4 square cards have been played side by side in line
so that the perimeter of the resultant space is 140 centimetre what is the area of each square card

Answer 1

As the perimeter is 140,, Since we placed 4 Square cards side by side , we get total of 10 Sides, So 10x=140,, here let x be length of side of square. So from that equation we get x=14,, we need to find area which is equal to x*x = 14*14=196. I hope this would help u
