the notice board is square so all it's sides will be equal that is equal to 50 cm
so the area of square board equals to 50×50 =2500
area of 8 notices of dimensions 12cm × will be 8 (12× 10) that will be 8× 120
now left area will be
area of board-area of 8 notices
2500-960
=...1540 CM ²
hope it's correct
