\quad \huge \quad \quad \boxed{ \tt \:Answer }


\qquad \tt \rightarrow \: length = 11 \: \: in


\qquad \tt \rightarrow \: width = 4 \: \: in

____________________________________


\large \tt Solution \: :

Let the measures be :

  • width = x

  • length = x + 7


\textsf{\large Area of rectangle :}


\qquad \tt \rightarrow \: Area = length \sdot width


\qquad \tt \rightarrow \: 44 = x \sdot(x + 7)


\qquad \tt \rightarrow \: {x}^(2) + 7x = 44


\qquad \tt \rightarrow \: {x}^(2) + 7x - 44 = 0


\qquad \tt \rightarrow \: {x}^(2) + 11x - 4x - 44 = 0


\qquad \tt \rightarrow \: x(x + 11) - 4(x + 11) = 0


\qquad \tt \rightarrow \: (x + 11)(x - 4) = 0

possible values of x = -11 and 4


\textsf{But the acceptable value of x = 4}

[ length or width of rectangle can't be negative ]


\qquad \tt \rightarrow \: length = x + 7 = 4 + 7 = 11 \: \: in


\qquad \tt \rightarrow \: width = x = 4 \: \: in
