The length of the photograph is <u> 10 </u> inches.
Explanation:
Given, Width of a photograph is x.
Length of the photograph is 3 inches longer than its width. i.e. x + 3.
Area of the photograph = x(x+3)
If its area is 70 square inches, then
x(x+3)=70
x(x-7)+10(x-7)=0
(x+10)(x-7) =0
x+10=0; x-7 = 0
x = -10 and x = 7
Width of the photograph must not be in negative value. So, we can ignore –10.
Therefore, width of the photograph, x = 7 inches.
Now, the length of the photograph = 7 + 3 = 10 inches.
Thus, the required length of the photograph is 10 inches.
Answer:
It will be 2.83 inches long on the drawing
Step-by-step explanation:
The scale we have is;
0.5 in to 3 ft
This;
x in to 17
17 * 0.5 = 3 * x
8.5 = 3x
x = 8.5/3
x = 2.83 inches
