Answer 2

Answer:

pls.. mark me as brainliest

Step-by-step explanation:

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
