It is given that PQRS is a square We know that every side in a square is equal in length âˆ´In square PQRS, PQ = QR = RS = SP Area of a square = $l^{2}$ Perimeter of a square = $4 l$ As it is given that PQ = QR = 20cm âˆ´l = 20cm âˆ´Area of square PQRS = $(20 c m)^{2} = 400 c m^{2}$ Perimeter of square PQRS = $4 (20 c m) = 80 c m$ Hope you get it
