Given : a rectangular gate is made using 6 straight pieces of steel. the weight of the the steel is 2.5kg per metre

To find : total weight of the steel gate

Solution:

Missing information :

Gate is of 5 m * 12 m  

two Horizontal rod  = 5 m each

two vertical rod   = 12 m each

two Diagonal rod   to be calculated  using Pythagoras theorem

Diagonal length² = 5² + 12²

=> Diagonal length² = 13²

=> Diagonal length = 13 m

Total length of Rod  = 2 ( 5 + 12 + 13)

= 2(30)

= 60 m

weight of the the steel is 2.5 kg per metre

Total Weight of Steel gate = 60 * 2.5  = 150 kg
