1.	Find the perimeter of the rectangle whose length is 40 cm and a diagonal is 41 cm.
Answer» We can create a rectangle ABCD with the given details. One side of rectangle `AB = 40` cm Diagonal of rectangle `AC = 41` cm So, other side of rectangle, `BC = sqrt(41^2-40^2)cm` `BC = sqrt(1681-1600) = sqrt81 = 9cm` So, Perimeter of rectangle ABCD, `P = 2(AB+BC)` `P = 2(40+9) = 2**49 = 98cm`
