The allowance of maximum area to a district for the attendance units in junior high schools of the district composed of grades to 9, inclusive, or to 10, inclusive, shall be determined pursuant to this section, rather than Sections and 16054. This

section does not apply to junior high schools composed of grades and only. There shall be allowed to each district a maximum area for the attendance units of the district in junior high schools determined by computing, in accordance with the following paragraph, the number of square feet for the attendance units at each junior high school attendance center of the district, and totaling the number of square feet so determined for all attendance units in all such junior high school attendance centers of the district.

There shall be allowed a maximum area of square feet for each attendance unit of the junior high attendance center in grades and 8. For each attendance unit in grade 9, or grades and 10, as the case may be, at each junior high school attendance center, there shall be allowed a maximum area of a number of square feet equal to the number of square feet which would be allowed under

Section for each attendance unit of an attendance center having a total number of attendance units equal to the total number of attendance units in grades to 9, inclusive, or to 10, inclusive, as the case may be, at the junior high school attendance center. The number of square feet which would be allowed under

Section for each attendance unit of an attendance center shall be computed by determining in accordance with that

section the total number of square feet which would be allowed at an attendance center and dividing such total number of square feet by the total number of attendance units at such attendance center.
