the width of a rectangular room is 4m wider tan its height and the length is 8m wider than the width .if the total area of the wall is 512m square, find the length of the room.

Answer 1

height is x,

width = x+4
length = w+8 = x+12

area of walls is 2x(x+4) + 2x(x+12) = 2x(2x+16) = 4x(x+8)

since 512 = 2^9, I guess 4*8*16=512 so x=8
