Questions 4 to 6

4.) Determine the area of each parallelogram.



They are drawn on centimetre grid paper.







a)
A = b x h
A = 2x4
A = 8cm squared






b)




A = b x h




A = 3 x 5




A = 15 cm squared








5.) Draw each of the following parallelogram on centimetre grid paper.




Use the formula to determine the area of each parallelogram.




Check your answers using estimation.














a) b = 4cm , h = 5cm









A = b x h



A = 4 x 5



A = 20cm squared









b) b = 3cm , h = 7cm





A = b x h

A = 3 x 7

A = 21cm squared



















6.) Draw each of the following parallelogram on centimetre grid paper.
Use the formula to determine the area of each parallelogram.
Check your answers using estimation.



a) h = 6cm , b = 4cm







A = h x b

A = 6 x 4

A = 24cm squared
