Length of a rectangular tank is twice its breadth. If the depth of the tank is 3 m and area of its four walls is 108m2 , find the length of the tank. |
|
Answer» Let breadth of the tank be x. ∴ Length of the tank = 2x. Area of the walls of the tank = 2(length + breadth) × depth. ∴ 108 = 2(2x + x)× 3 ∴ 108 = 18 x ∴ x = 6 ∴ 2x = 12 ∴ Length of the tank = 12m. tan R = PQ / QR = 3/4 |
