pass the line i drew and then you'll have a square (think about why its a square if you got those 90 angles). so its 4^2=16.

the other shape is a trapeze so if you know the area formula its (2+4)×4/2 = 12.

12+16 = 28.

if you don't know the trapeze formula you can do a square minus the triangular with bases of 4 and 2

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
