Question

25 This rectangular frame is made from 5 straight pieces of metal.

5 m
12 m
The weight of the metal is 1.5 kg per metre.
Work out the total weight of the metal in the frame.

Answer 1

Circumference of the ractangular = 12 + 12 + 5 + 5 = 34 m

Diagonal = sqrt{12^{2} + 5^{2}} = 13 m

Total length in meters = 34 + 13 = 47 m

Total weight in Kg = (47)(1.5) = 70.5 Kg
