"the figures are similar. the ratio of the lengths of their corresponding sides is 40: 45, or 8: 9. find the ratio of their perimeters and the ratio of their areas. the figures are not drawn to scale.

a) 9: 10 and 81: 100 .. b) 8.9 and 81: 100 .. c) 9: 10 and 64: 81 .. d) 8.9 and 64: 81"

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
