Answer 2

Answer:

The area of the formwork is 2.14 $m^2$.

Given:

A beam of 2m span and cross section dimension of 400\times 200 mm.

To find:

The area of framework

Solution:  

Cross section I terms of metres (400$\times$ 200 mm) = 0.4 $\times$ 0.2 m

Width and depth are given in cross section  

Area of the framework = (2$\times$ 0.4 $\times$2) + (2$\times$0.4 $\times$ 0.2) + (2 $\times$ 0.2)

= 2.14 $m^2$

Result:

The area of the formwork is = 2.14 $m^2$.
