Answer:

Question:

In the adjacent Quadrilateral ABCD, AC is the diagonal of length 36cm, BE and DF perpendicular from B and D to AC are 8cm and 12cm respectively. Find the area of the quadrilateral.

Answer:

Area of the given Quadrilateral = 860 cm²

Step-by-step explanation:

In the given figure we have two triangles, ∆ADC and ∆ABC.

The ∆ ADC, Base = 36cm and height = 12cm

Now, let's calculate the area of the ∆ ADC

\bf Area \ of \ \triangle ADC = \dfrac{1}{2} BASE \times HEIGHTArea of △ADC=

2

1

BASE×HEIGHT

\sf Area \ of \ \triangle ADC = \dfrac{1}{2} 36 \times 12Area of △ADC=

2

1

36×12

\sf Area \ of \ \triangle ADC = 18 \times 12Area of △ADC=18×12

\sf Area \ of \ \triangle ADC = 216cm^2Area of △ADC=216cm

2

The ∆ ABC, Base = 36cm and Height = 8cm

Now, let's calculate the area of the ∆ ABC

\bf Area \ of \triangle ABC = \dfrac{1}{2} BASE \times HEIGHTArea of△ABC=

2

1

BASE×HEIGHT

\sf Area \ of \ \triangle ABC = \dfrac{1}{2} 36 \times 8Area of △ABC=

2

1

36×8

\sf Area \ of \ \triangle ABC = 36 \times 4Area of △ABC=36×4

\sf Area \ of \ \triangle ABC = 144cm^2Area of △ABC=144cm

2

Area of Quadrilateral = ADC + ABC

Area of Quadrilateral = 216cm² + 144cm² = 360cm²
