If the area of triangle A with sides 5, 12, and 13 equals the area of rectangle B with height 5, what is the perimeter of the rectangle ?

Answer 1

5, 12, 13 is Pythagorean triple ... right triangle with integer sides
... the area is ... 1/2 * 5 * 12 = 30

for the rectangle ... 5 * w = 30

solve for w , then find the perimeter ... 5 + 5 + w + w
