Question

find the area of quadrilateral​

Answer 1

Answer:

6 cm ^2

Step-by-step explanation:

area of ABCD= area of ABC +area of ADC

area of ABCD = 1/2*4*1 + 1/2*4*2

area of ABCD = 2+4

area of ABCD = 6 cm^2

Answer 2

Answer:

(a) 6 cm²

Step-by-step explanation:

1. area of quadrilateral ABCD = area of ABC + area of ADC
2. area ofABC = 1/2 × base × height
3. area ofABC = 1/2 × 4 × 1 cm²
4. area ofABC = 2 cm²
5. area of ADC = 1/2 × base × height
6. area of ADC = 1/2 × 4 × 2 cm²
7. area of ADC = 4 cm²
8. area of quadrilateral = 2 cm² + 4 cm²
9. area of quadrilateral = 6 cm²
