Asha and Suman’s mud forts have heights 9 cm and 16 cm. They are 24 cm apart. How far (in cm)are the fort tops from each other ? |
25 24 7 16 |
25 |
From the above figure, DE = CD + CE = DE = AB + CE = CE = DE - AB = CE = 16 - 9 = CE = 7 cm In \(\Delta \)ACE, pythagoras theorem, \( {(AE) }^{2 } \) = \( {(AC) }^{2 } \) + \( {(CE) }^{2 } \) = \( {(AE) }^{2 } \) = \( {(24) }^{2 } \) + \( {(7) }^{2 } \) = \( {(AE) }^{2 } \) = 625 = AE = 25 cm Therefore, fort tops are 25 cm far from each other. |
