Question

Areas of two similar triangles are 225 sq.cm. and 81 sq.cm. If a side of the smaller triangle is 12 cm, then find corresponding side of the bigger triangle . [3 M] 2) Find the diagonal of a rectangle whose length is 35 cm and breadth is 12 cm. [3 M] 3) ΔAMT~Δ AHE. In Δ AMT, AM= 6.3 cm, ∠TAM = 5O°, AT= 5.6 cm. AM/AH = 7/5. Construct Δ AHE .​

Answer 1

Answer:

Let the areas of two similar triangles be A1 and A2 . A1 = 225 sq. cm. A2 = 81 sq. cm.  Let the corresponding sides of triangles be S1 and S2 respectively.  S1 = 12 cm

∴ The length of the corresponding side of the bigger triangle is 20 cm.
