Question

the perimeters of two similar triangles are 40 cm and 50 cm respectively the ratio of the area of first triangle to the area of second triangle is

Answer 1

16:25 will be the answer

Answer 2

HiAs we know that the ratio of perimeters of 2 similar triangles are equal to ratio of corresponding sidesI.e perimeter of 1st / perimeter of second = side of 1st / side of 2nd40 / 50 = side of 1st / side of 2ndside of 1st / side of 2nd = 4 / 5 We know that " The ratio of two similar triangles are equal to the square of ratio of there corresponding sidesarea of 1 st / area of 2nd = ( side of 1st / side of 2nd ) ^2 = (4 / 5 ) ^2= 16 / 25
