Answer :
Hiya Qwerty.
Find the area of a triangle it's easy, but we should know what type of triangle is.
We know it is not isosceles, since it has three different legs.
But we can also check if it is a rigt triangle. Those legs should soddisfy the Pythagorean Triple.
a^2+b^2 = c^2 (a and b are the legs and c the hypothenuse, longest side).
So, plug in the values.
15^2+20^2 = 25^2
225+400 = 625
625 = 625
We found out that it is a right triangle.
We know that a right triangle is half a square [see, the hypothenuse is the diagonal of the half square :)].
Then, we should apply the square area formula but divided by two.
A = (leg*leg)/2 = (15*20)/2 = 150 m^2
Hope it helped.
