1. Corresponding sides of
two similar triangles are in
the ratio of 3:5. If the area of
smaller triangle is 45 sq.cm,
then the area of larger
triangle is
125 sq.cm.
130 sq.cm.
108 sq.cm
152 sq.cm​

Answer 1

Answer:

125 sq.cm

Step-by-step explanation:

$(\frac{3}{5} )^{2} = \frac{45}{x} \\ \frac{9}{25} = \frac{45}{x} \\ \\ x = 25 \times 5 = 125$

theory used:

in 2 similar triangles the ratio of their areas is the square of the ratio of one of their sides
