Find the cost of constructing the

landscape if 10% extra grass sod and
concrete slabs are purchased in case some of the product breaks or is
defective.
Can anyone help me. No links please

both equations and proportions are better.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

-1   1/6.   you dont subtract the denominators
