Question

Sides of two similar triangles are in the ratio 3:7 what is the ratio of areas of these triangles

Answer 1

Answer:

9 : 49

Step-by-step explanation:

The ratio of sides=3 : 7

Ratio of altitudes=3 : 7

Ratio of areas=3*3/2 : 7*7/2

Ratio of Areas=3*3 : 7*7 {2 gets cut}

Ratio of Areas=9 : 49

Answer 2

A1 = 3

A2 = 7

two triangle are similar

A1 =S2

A2 =S2

theorem of area of similar triangle

A1 = 3

A2= 7. squareing both side

A1 = 9

A2= 49

therefore the ratio of area of two similar triangle is 9 : 49
