    the requested area is given by the subsequent formula: \[\Large A = \frac{{\left( {B + b} \right) \times h}}{2}\] where: B= 5-(-4)= 9 b= 3-(-2)= 5 h=5-1=4 so \[\Large A = \frac{{\left( {B + b} \right) \times h}}{2} = \frac{{\left( {9 + 5} \right) \times 4}}{2} = ...\]

    here we have to apply the same formula above. Now using the same symbols, we have: B=9-3=... b=7-5=... h=8-5=... \[A = \frac{{\left( {B + b} \right) \times h}}{2}\]

    here is your polygon: |dw:1433457778822:dw| is it right?

    we can write this: |dw:1433457854503:dw| so total area = 12+14= 26
