Question

4. The areas of two similar triangles are 196 cm- and 169 cm", if the median of the first triangle is 4 cm, then median
of other triangle is
(a) 7.31
(b) 1.73
(c) 3.71
(d) 1.37​

Answer 1

Answer:

Step-by-step explanation:

side of 1st triangle = 14

side of 2nd triangle = 13

so, 14/13 = 4/x

x = 4*13/14

= 3.71 cm

Answer 2

Answer:

3.71cm

Step-by-step explanation:

we know that,

ratios of two similar triangles median square is equal to be ratio of areas square.

so,

${4}^{2} \div {r}^{2} = 196 \div 169$

or,

${r }^{2} = 2704 \div 196$

or,

$r = 3.71cm$
