Mr. Martin is making a swimming pool in his garden. He has three options, he can either make a triangular swimming pool or a circular swimming pool. In the remaining section outside the swimming pool, he will plant grass seeds to have nice green grass outside the swimming pool area. He will need to work out how much he would have to pay for the grass seed if grass seed comes in bags that cover 20 m2 and costs $10. Your task is to work out which option is cheaper for him. Make diagrams and show clearly how you calculate the area and work out the price of grass seed under each option and finally decide which is the better option.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
