Question

four square card have been placed side by side in line. so that perimeter of resultant shape is 140 cm. what is the area of each squre card?

Answer 1

obviously it should be mentioned that each square card is of same side length.

let it be x units.
so legnth =4x and breadth =x .
2(4x+x) =140
5x=70
x=14.
area of each square is = 14*14 =196
