Next question need help to….thanks

1. l trpesium= setengah x (20+16) x 5 = 90 m²
50cm x 50 cm = 2500 cm² = seperempat m²
1 m² = 4 lembar
90 x 4 = 360 lembar

2. l = 2 $pi$ 14
= 88 cm²

3. l = pi r² = 616 m²
biaya = 616 x 200000 = 123.200.000
jwb = B

Rumus keliling lingkaran 2 x $frac{22}{7}$ x jari jari
= 2 x $frac{22}{7}$ x 14
= 88

Semoga membnatu 😀
