Find the area of the quadrilateral ABCD. Here, AC = 22 cm, BM = 3 cm, DN = 3 cm, and BM ⊥ AC, DN ⊥ AC
Solution:
Given: AC = 22 cm, BM = 3 cm, DN = 3 cm
Area of the ∆ ABC = 1/2 × base × height
= 1/2 × AC × BM
= 1/2 × 22 cm × 3 cm
= 33 cm2
Area of the ∆ ADC = 1/2 × base × height
= 1/2 × AC × DN
= 1/2 × 22 × 3
= 33 cm2
Area of the quadrilateral ABCD = Area of the ∆ ABC + Area of the ∆ ADC
= 33 cm2 + 33 cm2
= 66 cm2
