Question

please Find the Area of these quadrilateral​

Answer 1

Answer:

286.6m2

Step-by-step explanation:

In ∆CDE,

CD = √DE²+EC²

= √169+576

= √745

= 27.3m

DC = BA

So, DC = BA = 27.3m

Area of ∆ADC = 1/2(13)(27.3)

= 177.4m²

Area of ∆BAC = 1/2(8)(27.3)

= 109.2m²

Area of quadrilateral = 177.4+109.2

= 286.6 m²
