What are all the possible rectangles with a perimeter of 30cm and sides whose lengths are whole numbers?
Dimensions are given out as length by width 14cm by 1cm 13cm by 2cm 12cm by 3cm 11cm by 4cm 10cm by 5cm 9cm by 6cm 8cm by 7cm And the rest is all repeats of the above.
What is the area of a triangle that has sides of 9cm 12cm and 14cm?
53.5 square cm to 1 d.p. Use the cosine rule to find an angle. Then use: Area = 1/2*a*b*sin C
