Luas bangun tersebut adalah. tolong dijawab trimakasih.

Alas sgtg = 16 + 4 + 4 = 24
Mencari t sgtg
= 13" - 12"
= 169 - 144
= akar 25
= 5

L sgtg + L persegi panjang
( 1/2 . Alas . t ) + ( p . l )
( 1/2 . 24 . 5 ) + ( 16 . 15)
60 + 240
300cm"

Mohon diteliti lg kak

alas segitiga = 4+16+4 = 24
t segitiga = √13² - 12²
= √169 - 144
= √25
= 5
Lsegitiga = 1/2 × a × t
= 1/2 × 24 × 5
= 12 × 5
= 60
Lpersegi = 15 × 16
= 240
Lsegitiga + Lpersegi = 60 + 240
= 300 cm²
