[tex]100 = \frac{1}{2} 20 \times (b) \\ 100 = 10b \\ b = 10[/tex]

His mistake is in the formula for Area of triangle. The correct formula is:

[tex] A= \frac{1}{2}(base)(height) [/tex]

Given that, Area= 100 sq. meter and height = 20 meter

So,

[tex] 100 = \frac{1}{2}(base)(20)\\ \\ 100 = (base)(10)\\ \\ base = \frac{100}{10}=10 [/tex]

So, the base of the triangle will be 10 meter.
