WALT: Solve problems involving perimeter.
Drawings of different dinosaur enclosures have been given to
Professor Lockhart. He needs to know which enclosures will fit
the different dinosaurs. Can you help him by calculating the
perimeter of each enclosure? Write inside each enclosure which
dinosaurs could fit.
Stegosaurs needs a cage
with a perimeter fence of
at least 50m.
T-Rex needs an enclosure
of exactly 100m perimeter.
Triceretops needs a cage
with a perimeter bigger
than 50m but smaller
than 100m
Brontosaurus needs a
perimeter fence bigger
than 100m
Baryonyx needs a cage
with a perimeter fence
between 80m and 95m
Velociraptor is a small
dinosaur and needs a cage
with a perimeter of less
than 50m
