The length of the base and height of a triangle is 20 cm and 10 cm, respectively. If the area of the triangle is equal to the area of a rectangle whose length is 25 cm, then find the breadth of the same rectangle.
Show answer & explanation
Correct answer: D
Explanation
Area of the triangle = 1/2 × 20 × 10= 100 sq cm
Area of the rectangle = 100 sq cm
Width = 100 / 25 = 4 cm
