Answer:
The builder's drawing dimensions are 5 inches long and 3 inches wide.
Step-by-step explanation:
As given,
The dimensions of Rashida scale drawing = 20 inches long by 12 inches wide
Now,
Also given Rashida makes a scale drawing for a crate with a scale factor of 1:2
Now,
Let the actual dimensions of Rashida drawings = x inches long by y inches wide
⇒[tex]\frac{1}{2}x = 20 , \frac{1}{2}y = 12[/tex]
⇒x = 40 , y = 24
∴ we get
The actual dimensions of Rashida drawings is 40 inches long by 24 inches wide
Now,
Given, The builder crate with a scale factor of 1:8
So, The dimensions of builder's drawing is [tex]\frac{1}{8}(40)[/tex] inches long by [tex]\frac{1}{8}(24)[/tex] inches wide
∴ we get
The builder's drawing dimensions are 5 inches long and 3 inches wide.
