Solution

The correct option is C Both A and B
Length of the rectangle $= 5 m$
Width of the rectangle $= 4 n$
Perimeter of the rectangle = Length + Width + Length + Width
$= 5 m + 4 n + 5 m + 4 n$
$= 10 m + 8 n (5 m$ and 5m are one pair of like terms so they will be added, $4 n$ and $4 n$ are other pair of like terms so they will be added $)$

Algebraic expression: $10 m + 8 n$

$Terms$ $10 m$ $8 n$

$Coefficient$ 10 8

$Variables$ $m$ $n$

The coefficients of the algebraic expression $10 m + 8 n$ are $10$ and $8$ respectively.
Both A and B are correct.

Option D is the correct choice.
