Question

The figure shows the dimension of a rectangular wall having a window and a door of a room. what is the algebraic expressions for the area of the wall to be painted?

Answer 1

Hey There!

_____________________________

We have to paint the entire wall excluding Windows and Door

Area of Wall (W) = (4x+ 3)(4x)

= 16x^2 + 12x

Area of Window = (2x)(x)

= 2x^2

Area of Door = (3x)(x)

= 3x^2

Area to be painted = Area of wall - Area of window + Area of door

Ar to be painted = 16x^2 + 12 x - (2x^2 + 3x^2)

Ar to be painted = 16x^2 + 12x - 5x^2

Ar to be painted = +12x + 11x^2

11x^2 + 12x , That's the Algebraic Expression

NOTE : X^2 = (X) Whole Square
