26. draw out the model. find the difference between the boys and girls, 8 boys x $5 extra = $40. $180 - $40 = $140 will give you the 14 units. find one unit.
27. the perimeter is the outer corner. draw out the square for you to better visualise. since square has equal sides, divide the perimeter by 4 and you get 2/9m. area is length x breadth, 2/9 x 2/9 = 4/81
let me know if you require further explanation
