Question

the ratio of similar triangles are in the ratio 9: 4 find the ratio of their areas

Answer 1

area of tri. 1st 9x and 2nd 4x then,
ratio=1/2x9x divided by 4x=9 isto 4

Answer 2

The ratio of the areas of two similar triangle is equal to the square of their corresponding sides.

Therefore,

(9/4 ) square = area of first triangle/area of

second triangle

So ,81/16 = area of first triange/ area of second trainlge.
