Bangun persegi panjang
L = p × l
L = 5 × 7
L = 35
Bangun setengah lingkaran
r = 7 : 2 = 3,5
L = ½ × π × r × r
L = ½ × 3,14 × 3,5 × 3,5
L = 19,2325
Total Luas = 35 + 19,2325 = 54,2325
Jawaban:
persegi panjang = p x l
= 5 x 7
= 35 cm
bangun ½ lingkaran
l = ½ x π x r²
= ½ x 22/7 x 3,5²
= 19.2325 cm
gabungan = 19.2325 + 35 = 54,2325
