That's impossible. Are you factoring?
The sides of the rectangla are its length and width. We know the length is 5m longer than the width. Since we dont know the width, we can say that the width is x and the length is x+5.
The perimeter, as we know, is equal to the sum of all sides. We have two “length” sides and two “width” sides, so our equation is:
x + x + x+5 + x+5 = 46
Lets add all of this:
4x + 10 = 46
4x = 46-10
4x = 36
x = 36/4
x = 9
So our width is 9m and the length is 14m.
The area of a rectangle is width times length, so:
9*14=126m^2.
m is an unknown number that is being decreased by 7.
OPTION A IS WRONG BECAUSE MATHEMATICALLY IT IS WRITTEN AS

B IS WRONG BECAUSE IT MEANS

C IS WRONG BECAUSE IT MEANS

BUT D IS THE ANSWER BECAUSE IT MEANS

SINCE m IS TREATED AS AN UNKNOWN NUMBER.
GOODLUCK!!!!
If this is asking for written word then
Twelve times f plus Twenty-four.
