Question

find the area of quadrilateral ​

Answer 1

½*d1*d2 = Area of Rhombus. Hence, you can take the area of last two quadrilaterals using this method.

Answer 2

Answer:

Step-by-step explanation:

→ To find the area of 1st quadrilateral

→ We have to divide it into two triangles.

→ then find area of two triangles and add them so we will get area of quadrilateral.

→ Area of triangle = 1/2 × b × h

→ Area of triangle ABC

→ 1/2 × 6 × 3

→ 1/2 × 18

→ 18/2

→ 9 cm²

→ Area of triangle ADC

→ 1/2 × 6 × 5

→ 1/2 × 30

→ 30/2

→ 15 cm²

→ now add them :

→ 9cm² + 15cm² = 24 cm²

→ area of quadrilateral is 24cm².

→ Area of second quadrilateral

→ we will take straight right angle triangle

→ which have. h=4.6cm and b(base)=4.6cm

→ area of triangle = 1/2 × b × h

→ 1/2 × 4.6 × 4.6

→ 1/2 × 21.16

→ 21.16/2

→ 10.58 cm²

→ area of triangle of b=4.6cm and h=4.6cm

→ area of triangle = 1/2 × b × h

→ 1/2 × 4.6 × 4.6

→ 1/2 × 21.16

→ 21.16/2

→ 10.58cm²

→ now add them :

→ 10.58cm² + 10.58cm²

→ 21.16cm²

→ so area of second quadrilateral is 21.16 cm².

→ now third quadrilateral area:

→ area of triangle of b=8cm and h = 2cm

→ 1/2 × 8 × 2

→ 1/2 × 16

→ 16/2

→ 8cm²

→ Area of triangle with b=5cm and h=4cm

→ 1/2 × 5 × 4

→ 1/2  × 20

→ 20/2

→ 10cm²

→ now add the area:

→ 8cm² + 10cm²

→ 18cm²

→ so area of third quadrilateral is 18cm².
