1. Find the area of given quadrilateral:
B
с
3.8 cm
6 cm
A
7.2 cm
D​

Answer 1

Answer:

In triangle ABC, Area = 1/2 × BC × AC

Area of ABC = 1/2× 3.8 × 6 = 11.4 cm^2

In triangle ADC,

Area of ADC = 1/2 × 7.2 × 6 = 21.6 cm^2

Area of quadrilateral ABCD = 21.6 + 11.4 = 33 cm^2

Answer 2

Answer:

In triangle ABC, Area = 1/2 × BC × AC

Area of ABC = 1/2× 3.8 × 6 = 11.4 cm^2

In triangle ADC,

Area of ADC = 1/2 × 7.2 × 6 = 21.6 cm^2

Area of quadrilateral ABCD = 21.6 + 11.4 = 33 cm^2
