Given quadrilateral divided into two parts i)∆ABC ii)∆ACD
Area of triangle ABC=1/2×b×h =1/2×22×3=33cm²
Area of triangle ACD =1/2×b×h =1/2×22×3 =33cm²
Area of quadrilateral ABCD =area of triangle ABC+area of triangle ACD
Area of quadrilateral ABCD =33+33=66cm²
Area of triangle ABC=1/2×b×h =1/2×22×3=33cm²
Area of triangle ACD =1/2×b×h =1/2×22×3 =33cm²
Area of quadrilateral ABCD =area of triangle ABC+area of triangle ACD
Area of quadrilateral ABCD =33+33=66cm²
