Kak tolong pakai cara

L = 1/2xat
    = 120 cm²
a=24
t= L : 1/2 x a
 =120 : 1/2 x 24
 =120 / 12
 =10 cm

jawab.C

sisi miring = √24²+10²
                  =√576 + 100
                   =√676
                    =26 cm

K=a +t + sisi iring
  = 24+10+26
  =60 cm

semoga bantu yaaa

LΔ= 1/2 x a x t
120 = 1/2 x 24 x t
120 = 12 x t
120/12 = t
10 = t
lalu temukan Sisi miring menggunakan theorema phytagoras
sisi miring =√10^2 + 24^2
=√100 + 576
= √676
= 26 cm
maka keliling = a + t + sisi miring
= 24 + 10 + 26 = 60 cm
