What I think the area is 210

Step-by-step explanation:

Multiply the lengths. Hope this helps

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

is the correct option.
