Answer:
1920 cm^2 = T.S.A
Step-by-step explanation:
formula applied is {1/2 (perimeterof base x slant }+ area of base
area of base = a^2
area of square base= 900cm^2
perimeter = 4 x side
perimeter of square = 4x30=120cm
L.S.A= 1/2 x 120x 17= 1020 cm^2
T.S.A= L.S.A+ area of base
T.S.A= 1020 + 900
T.S.A= 1920cm^2
