Question

length of a rectangular tank is twice its breadth if the depth of the tank is 3m and the area of its four walls is 108m find the length of the tank

Answer 1

Let length be p and breadth be 2p

Area of 4 wall = 2(length + breadth) × h eight

=> 2(p + 2p ) × 3 = 108

=> 2 × 3p × 3= 108

=> 18p = 108

p = 108 ÷ 18  

p = 6 cm

Length = 6 cm  and Breadth = 12 cm
