A quadrilateral is divided into two triangles by a diagonal of 13 cm. If both triangles have height 12 cm, find total area.
Show answer & explanation
Correct answer: A
Explanation
Diagonal = 13 cm, Height = 12 cm
According to the formula: Area of a triangle = (1/2) × Base × Height
Area of one triangle = (1/2) × 13 × 12 = 78 cm²
Area of both triangles = 2 × 78 = 156 cm²
