Question

a) In Fig. (i) ABCD is a convex quadrilateral which has two diagonals AC and BD.

Answer 1

Answer:

Step-by-step explanation:

→ Given That : ABCD is a Quadrilateral in which diagonal BD = 64 CM , AL ⊥

BD  And CM ⊥ BD , AL = 13 . 2 CM AND CM = 16 . 8 cm

→ Area of Triangle Δ  ABD = 1/2 × BD × AL

                                       = 1/2 × 64 cm × 13.2 cm

                                        = 422.4 cm²

→ Area of Δ BCD = 1/2 × BD × CM

                             = 1/2 × 64 CM × 16.8 cm

                            = 537.6 cm²
