Question

A trapezoid has an area of 164 cm^2

I one base is 9 cm and the height is 12 cm
what is the length of the other base​

Answer 1

55/3 cm

Explanation:

The formula for the area of a trapezoid is:

`h*(1)/(2)(b1+b2)` where h is the height and b1 and b2 are the two bases.

We can set up the equation:

`12*(1)/(2)(9+x) = 164`

Solving, we get x = 55/3
