Explanation:
Given:
Length of Rectangle is 16 cm more than its breadth.
Perimeter of Rectangle = 148 cm
⠀⠀⠀⠀⠀⠀⠀
To find:
Length and breadth of Rectangle?
⠀⠀⠀⠀⠀⠀⠀
Solution:
⠀⠀⠀⠀⠀⠀⠀
☯ Let breadth of rectangle be x cm.
☯ Therefore, Length of rectangle (x + 16) cm.
⠀⠀⠀⠀⠀⠀⠀
\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large (x + 16) cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large x cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}
⠀⠀⠀⠀⠀⠀⠀
\begin{gathered}\underline{\bigstar\:\boldsymbol{According\: to\:the\:question\::}}\\ \\\end{gathered}★Accordingtothequestion:
\begin{gathered}:\implies\sf 2(x + (x + 16)) = 148\\ \\\end{gathered}:⟹2(x+(x+16))=148
\begin{gathered}:\implies\sf (x + (x + 16) = \cancel{\dfrac{148}{2}}\\ \\\end{gathered}:⟹(x+(x+16)=2148
\begin{gathered}:\implies\sf (x + (x + 16) = 74\\ \\\end{gathered}:⟹(x+(x+16)=74
\begin{gathered}:\implies\sf 2x + 16 = 74\\ \\\end{gathered}:⟹2x+16=74
\begin{gathered}:\implies\sf 2x = 74 - 16\\ \\\end{gathered}:⟹2x=74−16
\begin{gathered}:\implies\sf 2x = 58\\ \\\end{gathered}:⟹2x=58
\begin{gathered}:\implies\sf x = \cancel{ \dfrac{58}{2}}\\ \\\end{gathered}:⟹x=258
\begin{gathered}:\implies{\boxed{\sf{\pink{x = 29}}}}\;\bigstar\\ \\\end{gathered}:⟹x=29★
Therefore,
Breadth of Rectangle, x = 29 cm
Length of Rectangle, (x + 16) = 45 cm
⠀⠀⠀⠀⠀⠀⠀
∴ Hence, Length and Breadth of rectangle is 45 cm and 29 cm respectively.
ANSWER
A polynomial is an algebraic expression containing two or more terms.
Also, it requires the exponents of the variables in each term should be positive integers.
A, B, D do not satisfy this property
Hence, C is correct.
