Penyelesaian :

Sisi = 3,5 cm × 2 = 7
Luas persegi
= 7 cm × 7 cm
= 49 cm^2

Luas lingkaran
= 3 × 1/4 × phi × r × r
= 3 × 1/4 × 22/7 × 3,5 cm × 3,5 cm
= 28,875 cm^2

Luas daerah yang diarsir
= Luas persegi - Luas lingkaran
= 49 cm^2 - 28,875 cm^2
= 20,125 cm^2

L persegi
= s × s
= 7 × 7
= 49 cm²

L 3/4 lingkaran
= 3/4 × Π r²
= 3/4 × 22/7 × 3,5 × 3,5
= 3/4 × 22/2 × 3,5
= 3/4 × 11 × 3,5
= 3/4 × 38,5
= 115,5/4
= 28,875 cm²

L daerah yang diarsir
= 49 cm² - 28,875 cm²
= 20,125 cm²
