The height of a triangle is 3 m more than its base. If the area of the triangle is 35 sq.m. , then find its height.
The correct option is A 10 m
Let x be the height of the triangle, then (x−3) will be the base.
Area of a triangle =12×base×height
⇒x=10 or (−7)
x cannot be a negative value. So x=10.
∴ The height of the triangle is 10 m.
