Year 5 - Post-Assessment - Shape and Space

A school wants to put a fence around its field. The field

is an L shape.

Here are some of the measurements around the field:

How much fence is needed for length A?

• 92 M

• 25 M

• It is impossible to calculate the answer. The only way she can work out length A is to measure it.

• 17 M

Which of the following shapes is an irregular polygon?

• A

• B

• C

• D

Two swimming pools are next to each other. The

learners’ pool (A) is a rectangle. The main pool (B)

is a square.

Tom swims the width of the main pool (the

distance shown by the question mark).

How can he work out the distance he has swum?

• He needs to add 4 m and 3 m. A square’s sides are all equal, so this

  length is the same as the main pool’s width. Tom swam 7 m.

• He needs to add all the distances shown. Tom swam 12 m.

• The main pool is a square, so the unknown distance the distance of 4 m

  that is labelled. Tom swam 4 m.

• It is impossible for Tom to work out how far he swam with this

  information. He needs to be given one more distance.

Which of these fields would you need a fence 126m long to surround?

• A

• B

• C

• D

Which of these shapes does not have an area of 64 cm2?

• A square with side length 8cm

• A rectangle with length 32cm and width 2cm

• A shape made from two identical rectangles placed end to end (each with a length of 16cm and a width of 2cm)

• A rectangle with length 32cm and width 32cm

Alisha has two rectangular notebooks.

She puts them together to make an L shape.

Alisha draws around the shape that she has made.

What is the perimeter of her shape?

• 230 cm²

• 43cm

• 86cm

• 70cm

Four children are discussing an irregular shape.

Only one of them is correct. Who is it?

• 
• 
• Christopher says, “We can’t estimate the area of

  this shape because it’s not made up of whole

  squares. There are lots of part squares too.”
