Question

Find the area and the perimeter of a triangle that has a base of 20 inches, and two sides of 10 inches each. The altitude (height) is 8 inches.

Answer 1

Triangle with such sides does not exist because for sides of the riangle the inequality doesn't hold( the triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than the
length of the remaining side):
10+10 is not greater than 20, 10+10=20
