Question

Find the area of the following quadrilaterals the answer should be 16.5cm wrote answer in full details​

Answer 1

Answer:

16.5cm²

Step-by-step explanation:

AREA OF TRIANGLE ABC= ½×b×h

1/2× 6×3.5

= 10.5cm²

AREA OF TRIANGLE ADC= ½×b×h

1/2× 6 ×2

=6cm²

TOTAL AREA OF QUADRILATERAL = AREA OF TRIANGLE ABC + AREA OF TRIANGLE ADC

10.5+6

16.5cm²

Answer 2

Step-by-step explanation:

Area of ABCD = Area of ABC + Area of ADC

Area of ABC = 1/2 × AC × BM

= 1/2 × 6cm × 3.5cm

= 1/2 × 21cm

= 10.5cm²

Area of ADC = 1/2 × AC × DL

= 1/2 × 6cm × 2cm

= 1/2 × 12cm

= 6cm²

Area of ABCD = 10.5cm² + 6cm²

= 16.5cm²
