What is the area of this irregular figure?

Step-by-step explanation:

This figure is made up of  rectangle and a parallelogram

The area of a rectangle is:

And the area the parallelogram is it's height times length. The height of the parallelogram is , and it's length is

Therefore the area of the parallelogram is:

Together the area of the irregular shape is

Which is our answer.

answer: 20

step-by-step explanation:

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
