1.5 m
0.9 m
3.5 m
1.2 m​

Answer 1

Answer: 9.48$m^{2}$

Step-by-step explanation:

• We need to find the area of wood required to cover the frame.
• Area of the slant rectangular face=(3.5×1.5)$m^{2}$

                                                                  =5.25$m^{2}$

• Area of back rectangular face=(0.9×3.5)$m^{2}$

                                                          =3.15$m^{2}$

• Area of two side triangular face=2$(\frac{1}{2}*1.2*0.9)$$m^{2}$

                                                             =1.08$m^{2}$

• ∴ Total area of wood required=(5.25+3.15+1.08)$m^{2}$

                                                          =9.48$m^{2}$

• Hence,total area of wood required is 9.48$m^{2}$.
