Answer:
There's two ways to solve this.
Step-by-step explanation:
First way:
Let's divide the width and length by 2.3.
46÷2.3=20
69÷2.3=30
20×30
600 ft²
Second Way:
Let's find the area of the actual room.
46×69
3,174 ft²
Let's find the scale drawing squared.
2.3²=5.29
3,174÷5.29
600 ft²
It would be 69 inches long m8
10 depending on where the parentheses are

=gradient

Perpendicular gradient therefore is

With this info, y-y1=m(x-x1)
5(y-8)=-1(x-6)
5y-40=-x+6
5y=-x+46
