No 2 dong yg baik bantuin ya makasihh

a) AC = √(4^2 + 4^2)
= √32
= 4√2 cm

AK = √( (4√2)^2 + 1^2)
= √33 cm

LG :

LP = √(4^2 + 1^2)
= √17

LG = √(LP^2 + PG^2)
= √((√17)^2 + 3^2)
= √17+9
= √26 cm

b) AC = √(AB^2 + BC^2)
=√(5^2 + 4^2)
=√41 cm

EG =√(EH^2 + HG^2)
= √(4^2 + 4^2)
= √32
= 4√2 cm

DF = √((4√2)^2 + 4^2)
= √32+16
=√48
= 4√3 cm

AG =√((4√2)^2 + 4^2)
= √32+16
=√48
= 4√3 cm
