Question

Saya bingung mencari sisi miring karena di google itu rumusnya dikurangi tapi kata guru saya ditambah please jawab pake cara

Answer 1

DE=√15^2 - 9^2
= √225-81
= √144
= 12

k = AB+BC+CD+DE+EA
= 15+10+9+12+10
= 56 cm

Semoga membantu...

Answer 2

ED = √EC² - CD²
ED = √15² - 9²
ED = √225 - 81
ED = √144
ED = 12 cm

K = AB + BC + CD + DE + EA
K = 15 + 10 + 9 + 12 + 10
K = 56 cm

semoga membantu ^-^
