Question

Quadrilaterals A and B are similar. Find the values of the sides marked x and y :

Answer 1

x = 35 , y = 4

Explanation:

since the quadrilaterals are similar then the ratios of corresponding sides are in proportion , that is

`(x)/(10)` =
`(21)/(6)` ( cross- multiply )

6x = 210 ( divide both sides by 6 )

x = 35

and

`(y)/(14)` =
`(6)/(21)` ( cross- multiply )

21y = 84 ( divide both sides by 21 )

y = 4
