bearhunter [10]

Answer:

The expression is equal to \frac{150}{4^{2}}

The area of the scale drawing is 9.375\ ft^{2}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

let

z------> the scale factor

x------> the area of the actual room

y-----> the area of the scale drawing

so

z^{2}=\frac{x}{y}

we have

z=4

x=150\ ft^{2}

substitute and solve for y

4^{2}=\frac{150}{y}

y=\frac{150}{4^{2}}=9.375\ ft^{2}

1. 
The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side 
= 39* (6/(6+4+3)
= 39*6/13
=18

2. 63 breads : 35 kg flour
is the same as 
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
