Given :-

  • Ratio of areas of the triangle = 5:4
  • Ratio of height of the triangle = 4:5

To Find :-

  • Ratio of their bases.

Solution :-

Ratio of the areas two triangles  = Ratio of product of their bases and heights.

\:\:\:\:\:\:\hookrightarrow\:\:\:\sf\purple{5 : 4 = ( B \times 4 ) : ( b \times 5 )}

\:\:\:\:\:\:\hookrightarrow\:\:\:\sf\purple{\dfrac{5}{4}  = \dfrac{4b}{5b} }

\:\:\:\:\:\:\hookrightarrow\:\:\:\sf\purple{ 5 \times 5b = 4b \times 4}

\:\:\:\:\:\:\hookrightarrow\:\:\:\sf\purple{25b = 16b }

\:\:\:\:\:\:\hookrightarrow\:\:\:\sf\purple{\dfrac{25}{16}  = \dfrac{b}{b}  }

∴ Ratio of the bases = b:b  = 25:16

  • Ratio of height of the triangle = 4:5

To Find :-

  • Ratio of their bases

Solution :-

Ratio of the areas two triangles = Ratio of product of their bases and heights

 \longmapsto \sf\orange {5 : 4 = ( B \times 4 ) : ( b \times 5 )} \\

 \longmapsto \sf \orange {\dfrac{5}{4} = \dfrac{4B}{5b} }\\

 \longmapsto \sf\orange{ 5 \times 5b = 4B \times 4}\\

 \longmapsto \sf\orange{25b = 16B }\\

 \longmapsto \sf\orange{\dfrac{25}{16} = \dfrac{B}{b} }\\

Ratio of the bases = B:b = 25:16
