Question

I need help I have to find the area of the composite figure

Answer 1

Try cutting them into two separate squaesand finding the areas separately then adding the areas. the first square would be 20 x 21 which would be 420 and the second area could be found using 18 x 18 whiichwould be 324. If you add 420+324, you get the area of the whole shapewhich would be 744. I hope this helps :P

Answer 2

We divide the figure into two pieces, as shown in the attached diagram.

We get a rectangle with dimensions
`20 \ cm * 21 \ cm` plus a square with dimensions
`18 \ cm * 18 \ cm`. The area of the rectangle is
`420 \ cm^2` and the square is
`324 \ cm^2`, which together add up to
`744 \ cm^2`.
