No.22 tolong yah kakak

panjang sisi BD = √25^2-15^2=√625-225=√400=20

tarik garis B kebawah misalkan titik O,shg panjang BO= AE =16cm,jadi panjang OD = √20^2-16^2=√400-256=√144=12

panjang ED = 14+12 = 26

Luas trapesium = 1/2 x (AB+ED) x t
= 1/2 x 14 x 26 x 16
= 320

luas segitiga = 1/2.a.t
= 1/2 x 15 x 20
= 150

jadi luas total = 320+150=470 cm^2
