: 10 x 10 / 2 = 100/2 = 50 m²
Trus Persegi panjang:
3 x 10
= 30 m²
Yg diatas persegi panjang:
3 meter punyanya si persegi panjang itu alasnya segitiga, Jadi:
3 x 3 / 2 = 9/2 = 4.5 m²
Luasnya : 2.segitiga samping persegi panjang + Persegi panjang +`1 segitiga diatas persegi panjang = 2 x 50 + 30 + 4,5
= 100 + 30 + 4.5
= 174,5 cm²
