Question

find area of the following polygons​

Answer 1

Answer:

hi ,

Step-by-step explanation:

area of  rectangle = L*B

                             = 35cm * 12cm

                             = 420cm.sq

area of one triangle = A=hb/2

                                  = base =18cm ; length = 10cm  

                                   =90

total triangle = 4

total area of four triangle = 90*4

                                          = 360cm 4

      total area of polygon =  360 cm. sq +  420cm.sq

                                           = 780cm.sq
