thermal expansion of an isotropic object may be imagine as a photographic enlargement . so if there is a hole d1 & d2 in metal sheet. the area of hole will increase when body expends on heating,just as if the hole were solid of the same material.
expansion of area of the body will be independent of shape and size of hole.
