the lengths of the side of a rectangular window have the ratio 1.7 to 1 the area of the window is 2,720 sqaure inches what are d
nignag [31]

Answer:

Lenght: 68\ in\\\\Width: 40\ in

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

A=lw

Where "l" is the lenght and "w" is the width.

You know that the ratio  of the sides of the rectangular window is:

1.7:1

 Then, let be x the width (in inches) of the rectangular window and 1.7x the lenght (in inches) of the rectangular window.

Knowing that the area of the window is 2,720 square inches, you can know that:

(1.7x)(x)=2,720

Now you must solve for "x" in order to find the width:

(1.7x)(x)=2,720\\\\1.7x^2=\\\\x=\sqrt{\frac{2,720}{1.7} }\\\\x=40

Finally, the lenght is:

1.7x=1.7(40)=68

Replace the variable with 65 to double check.
4 (65) + 90 = 350
