First find the area of 1 tile
= length * breadth
= 8 * 5
= 40= 40/10000 = 0.004
no. of tiles= 1000
therefore, total area of 1000 tiles = area of room= 1000*0.004

Step-by-step explanation:
Find the rate of change between first two ordered pairs and the second two ordered pairs:
1. Points (2,4) and (3,9). Rate of change:
2. Points (3,9) and (4,16). Rate of change:
The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.
