Step-by-step explanation:
Area of a square ABCD = (Side)² = 36 cm² = 6²
AB=BC=CD=DA=6 cm
Let P is the midpoint of AB, Q is the midpoint of BC, R is the midpoint of CD and S is the midpoint of DA.
To evaluate the area of square PQRS, find value of PQ.
In △PQB
PB=1/2 ×AB = 6/2 = 3 cm and
BQ=1/2 ×BC = 6/2 = 3 cm
PQ²=PB²+BQ²=(3)²+(3)²=9+9=18=(3√2)²
Or, PQ = 3√2 cm
PQ=QR=RS=SP=3√2 cm
Area of the square PQRS = (Side)² = (3√2)² = 18 cm²
Therefore, Area of the square PQRS = 18 cm²
