The area of triangle is half the area of square. the perimeter of the square is the 224 cms. what is the area of the triangle? A) 1856cm sq. B) 1658cm sq. C) 1558cm sq. D) 1586cm sq. E) None of these
Find the length of the sides of the sq., s
Area of sq. = s^2
etc
Perimeter of square = 4s, therefore
4s = 224 and
s = 56
now space of sq. = s^2 = 56^2 = 3136 and
area of triangle = 3136 / a pair of = 1586 cm^2
