Option B
Length and width of rectangle is 15 inches and 6 inches respectively
<h3><u>
Solution:</u></h3>
Given that area of a rectangle is 90 square inch
Ratio of length to the width = 5: 2.
Need to determine length and width of rectangle.
As ratio of length to the width is 5 : 2
Lets assume length of rectangle = 5x inches and width of rectangle = 2x inches.
<em><u>The formula for area of rectangle is given as:</u></em>

Substituting the given value of area of rectangle and assumed value of length and width of rectangle we get:

On solving the above expression for x we get


Hence length and width of rectangle is 15 inches and 6 inches.
