The rectangle below has a total perimeter of 125 cm:

write an equation and solve it to find the length of the longer side of the rectangle.
2x + 10 = 125; x = 57.5 cm
x + 5 = 125; x = 120 cm
5x = 125; x = 25 cm
25x = 125; x = 5 cm

2x + 10 = 125; x = 57.5

Step-by-step explanation:

answer is c

step-by-step explanation:

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

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

is the correct option.
