200

Area Question 2 on 'Area Sheet'

(6 x 4) ÷ 2 = 

24 ÷ 2 =

12cm²

Area Question 3 on 'Area Sheet'

(5 x 6) + (4 x 9) = 

30 + 36 = 

66m²

Area Question 5 on 'Area Sheet'

A = (6 x 5) ÷ 2 = 15ft²

B = 9 x 6 = 54ft²

C = 6 x 4 = 24ft²

A + B + C = 93ft²

Perimeter

Perimeter Question 1 on 'Perimeter Sheet'

8 + 8 + 3 + 3 = 

22cm

200

Perimeter Question 2 on 'Perimeter Sheet'

9 + 13 + 18 = 

40in

(7 is the height, it is not an edge/side!)

Perimeter Question 3 on 'Perimeter Sheet'

10 + 9 + 4 + 4 + 6 + 5 =

19 + 8 + 11 =

30 + 8 =

38m

Perimeter Question 4 on 'Perimeter Sheet'

13 + 2 + 1 + 12 + 5 + 12 + 7 + 2 = 

16 + 12 + 17 + 9 = 

28 + 26 =

54cm

500

Perimeter Question 5 on 'Perimeter Sheet'

Length of c: a² + b² = c²

So, (6² + 8² = c²) = (36 + 64 = c²) = (100 = c²)

10² = 100 so c = 10.

Perimeter: is 6 + 8 + 10 = 24m.

If 28 x 32 = 896 

Then...

28 x 0.32 = ?

28 x 0.32 = 8.96

(Because 0.32 is 100x smaller than 32).

400

What are the next 2 numbers in this sequence?

1, 1, 2, 3, 5, 8, ___, ___

1, 1, 2, 3, 5, 8, 13, 21

This is the Fibonacci sequence. The next number is the total of the previous 2 numbers.

Five people were eating apples. 

A finished before B, but behind C. D finished before E, but behind B. What was the finishing order?

CABDE. 

Putting the first three in order, A finished in front of B but behind C, so CAB. Then, we know D finished before B, so CABD. We know E finished after D, so CABDE.
