jawab ya no 2 nya ajah

Ada 6 luas yang harus dihitung.
Yaitu ABFE, BCGF, DCGH, ADHE, ABCD, dan EFGH

Luas ABFE (trapesium)
= 1/2 × (AE + FB) × AB
= 1/2 × (5+8) × 4
= 26

Luas BCGF (persegi panjang)
= BC × CG (CG = FB = 5)
= 6 × 5
= 30

Luas ABFE = DCGH (trapesium)
Luas DCGH
= 26

Luas ADHE (persegi panjang)
= AD × AE (AD = BC = 6)
= 6 × 8
= 48

Luas ABCD (persegi panjang)
= AB × BC
= 6 × 4
= 24

Mari kita cari EF dulu pakai pitagoras
EF = akar (3^2 + 4^2)
EF = akar (9 + 16)
EF = akar (25)
EF = 5 cm

Luas EFGH (persegi panjang)
= EF × FG (FG = BC = 6)
= 5 × 6
= 30
