Answer:

Question no. 1

answer

So, Area of the Quadrilateral ABCD=936 cm^{2}ABCD=936cm^2

Step-by-step explanation:

Given;

For a quadrilateral ABCD

AB=28cm , BC=26 cm ,CD=50 cm , DA=40 cm and diagonal AC=30

From figure,

By Heron's formula;

Area of triangle ABC=

√S (s-a) (s-b) (s-c) so where

s =  \binom{a + b + c}{2}

SO ,

S= √42 (42-28) (42-26) (42-30)

area \: of \: abc =  {336}^{2}

Similarly

By Heron's Formula

Area of ∆ ADC=

√S (s-a) (s-b) (s-c) where

s =  \binom{a + b + c}{2}

SO,

S= 40+50+30/2= 60

S=60

Now Area of ADC

√60 (60-40) (60-50) (60-30)

Area of ∆ ADC=

600 {cm}^{2}

Area of Quadrilateral ABCD=

 {300 + 600cm}^{2}  = 936 {cm}^{2}

Area of Quadrilateral ABCD=

936 {cm}^{2}

Thanks
