For Square ABCD, Coordinates of A and C are given as (3, 5) and (0, 2) respectively.
So, we can find the length of diagonal for square ABCD. AC = √(0 − 3)^2 + (2 − 5)^2 = 3√2
If we have a length of diagonal AC, we can find out the area of the square.
Area of square = 1/2 (𝑝𝑟𝑜𝑑𝑢𝑐𝑡 𝑜𝑓 𝑑𝑖𝑎𝑔𝑜𝑛𝑎𝑙𝑠)
Area of Square ABCD = 1/2 × 3√2 × 3√2 = 9 Square units
For rectangle PQRS, as coordinates of P and R are given as (3, - 4) and (4,6), we can find out the length of diagonal PR. PR = √(4 − 3)^2 + (6 + 4)^2 = √101
Area of the rectangle is maximum, when it is a square.
So maximum area of Rectangle PQRS = 1/2× √101 × √101 = 101/2 square units.
Minimum area of Rectangle PQRS could go close to Zero as well.
Area of rectangle PQRS varies from a ‘value close to zero’ to 101/2 square units.
As it varies, we cannot compare the area of Rectangle PQRS to the area of Square
ABCD.
