jika jawaban saya membantu, mohon jadikan jawaban terbaik
L= I/2 × dI × d2
300= I/2×25×d2
600= 25×d2
d2 = 600/25
= 24 cm
mencari sisi miring segitiga
pertama d2/2= 24/2 = I2 cm
gunakan rumus phytagoras
s pendek=√9²+I2²
= √8I+I44
= √225 = I5 cm
s panjang= √I6²+I2²
= √256+I44
= √400 = 20 cm
Keliling= 2(s pendek+s panjang)
= 2(I5+20)
= 2(35)= 70 cm
