step 1: find the area of each of the squares by squareing them.

step 2: add all the you made in step 1 to make 1058.

step 3: factorise the number(1058) to make the nubers 23 23 and 2.

step 4: make different rectangles (some will not work because they are either toobig or too small but don't worry) until you find one which area is 1058.

the answer is 23 x 46.
