a) Chu vi hình chữ nhật ABCD là: (45+15)x2=120 (cm)

b) Cạnh EB=AB-AE=45-15=30 (cm)

Diện tích hình thang EBCD là: (45+30)x15:2=562,5 (cm²)

c) Cạnh MB=MC=BC:2=15:2=7,5 (cm)

Diện tích tam giác DMC là: 45 x 7,5 : 2= 168,75 (cm²)

Diện tích tam giác EBM là: 30 x 7,5 : 2 = 112,5 (cm²)

Diện tích tam giác EDM = S_EBCD-(S_DMC+S_EBM) = 562,5 - (168,75+112,5) = 281,25 (cm²)
