Answer:

The height of the tabletop is 65.5 centimeters.

Step-by-step explanation:

We are given that,

Length of the base = 115 centimeters

Width of the base = 85 centimeters

Area of the trapezoid shaped base = 6,550 square centimeters.

Since, we know,

Area of a trapezoid = [tex]\frac{Length+Width}{2}\times Height[/tex]

So, we get,

[tex]6550=\frac{115+85}{2}\times Height[/tex]

i.e. [tex]6550=\frac{200}{2}\times Height[/tex]

i.e. [tex]6550=100\times Height[/tex]

i.e. [tex]Height=\frac{6550}{100}[/tex]

i.e. Height = 65.5 centimeters

Hence, the height of the tabletop is 65.5 centimeters.
