Answer 1

951 is your answerrrrr

Answer 2

Okay, her brother drawings are 43.5 cm by 934 mm.

First thing we need to do id get alike measurements. 
1 cm = 10 mm.

Multiply 43.5 by 10          934 mm = 435

Now since we are framing something we need to find the perimeter. 

Write an equation: P= cm of wood= w     

w= 2(43.5)+2(435)

Simplify:
w=951

Answer:
951 cm of wood
