Luas gabungan
= Luas persegi panjang + Luas persegi panjang - Luas 1/2 lingkaran
= p x l + p x l - 1/2 x π x r²
= 17 cm x 14 cm + 13 cm x 7 cm - 1/2 x 22/7 cm x 7 cm x 7 cm
= 238 cm² + 91 cm² - 77 cm²
= 252 cm²

Luas gabungan bangun diatas= Luas persegi panjang + Luas persegi panjang - Luas 1/2 lingkaran
= (p x l) + (p x l) - (1/2 x π x r²)
= (17 cm.14 cm) + (13 cm.7 cm) - (1/2.22/7 cm.7 cm.7 cm)
= 238 cm² + 91 cm² - 77 cm²
= 252 cm²
