You already know the length and the width. That means you also know the area of the floor. 7 x 5 = 35. You divide 130 by 35. That will give you about 3.7. The height of the room is 3.7cm

Y = –x2 + 4x + 12
y = –3x + 24
so
–x2 + 4x + 12 = –3x + 24

x^2 -7x + 12 = 0
(x - 4)(x - 3) = 0
x - 4 =0; x =4
x - 3 = 0; x= 3

y = –3x + 24 = -3(3) + 24 = -9+24 = 15 (when x = 3)
y = –3x + 24 = -3(4) + 24 = -12+24 = 12 (when x = 4)

answer
(3, 15) and (4, 12)
