The area of rectangle is 15x - 25y + 30 sqaure units
<em><u>Solution:</u></em>
Given that, a rectangle with a length of 5 and a width of 3x - 5y + 6
To find: Area of rectangle
<em><u>The area of rectangle is given by formula:</u></em>
From given,
Length = 5
Width = 3x - 5y + 6
<em><u>Substituting the values in formula, we get,</u></em>
Thus area of rectangle is 15x - 25y + 30 sqaure units
