Two poles are ,18 cm and 13 cm high ,stand upright in a playground .If their feet are 12 m apart ,find the distance betweeen their tops.
Let AD and CE are two poles of height 18 cm and 13 cm respectively.
And, distance between these two poles (DE) = 12 m = 12100 = 1200 cm
BD = CD = 13 cm
So, AB = AD - BD = 18 - 13 = 5 cm
Hence, distance between their tops is 1200 cm.
