Two triangle are similar. a side ofone is 2 unit long. the corresponding side of the other is 5 unit long. waht is the ratio of their perimeter and their areas

see explanation

Step-by-step explanation:

Given 2 similar figures with ratio of corresponding sides = a : b

Then the ratio of the perimeter is also = a : b

and ratio of areas = a² : b²

Here ratio of sides = 2 : 5, thus

ratio of perimeters = 2 : 5 and

ratio of area = 2² : 5² = 4 : 25
