Answer:
41
Step-by-step explanation:
We know that complex numbers are a combination of real and imaginary numbers
Real part is x and imaginary part y is multiplied by i, square root of -1
Modulus of x+iy =
Here instead of x and y are given 9 and 40
i.e. 9+40i
Hence to find modulus we square the coefficients add them and then find square root
|9+49i| =
By long division method we find that
|9+40i| =41
Let the width be W, then the length is 4W (since the width is 1/4 the length)
The area of the original deck is
The dimensions of the new deck are :
length = 4W+6
width=W+2
so the area of the new deck is :
"<span>the area of the new rectangular deck is 68 ft2 larger than the area of the original deck</span>" means that we write the equation:
the length is
ft
Answer: width: 4, length: 16
