Luas Persegi panjang besar
Panjang = 17 cm
Lebar = 7 cm + 7 cm = 14 cm

Luas = p x l
         = 17 cm x 14 cm
         = 238 cm²

Luas Persegi panjang kecil
Panjang= 30 cm - 17 cm = 13 cm
lebar = 7 cm

Luas = p x l
         = 13 cm x 7 cm
         = 91 cm²

Luas setengah lingkaran
r = 7 cm

Luas = 1/2.π.r²
         = 1/2 x 22/7 x 7 cm x 7 cm
         = 11 x 7 cm
         = 77 cm²

Luas keseluruhan
Luas = 238 cm² + 91 cm² - 77 cm²
         = 252 cm²
