Tolong di jawab ya kak

Jawaban:

A. Luas segiempat

= S × S

= 5 × 5

= 25cm

Keliling segiempat

= s + s + s + s

= 5 + 5 + 5 + 5

= 20cm

B. Luas Persegi panjang

= P × L

= 10 ×5

= 50cm

Keliling Persegi panjang

= 2 ( p+ l )

= 2 ( 10 + 5 )

= 2.15

=30 cm

C. LuasSegitiga

= 1/2 × a × t

= 1/2 ×12 ×6

= 1/2 × 47.232

= 47.232/2

= 23.616cm

Keliling Segitiga

= 12 + 12 + 12

= 36cm
