To find the length of x, we need to use the formula for the area of a triangle:

Area = 1/2 * base * height

Given that the area of triangle ABC is 40 cm², we can set up the equation as follows:

40 = 1/2 * 10 * x

Solving for x:

40 = 5x

x = 40/5

x = 8

So, the length of x is 8 cm, rounded to three significant figures.
