10. Given 11. Find the area of an equilateral triangle with an edgelength of 8.37 cm 12. An isosceles triangle has edgelengths of 5.67 and 12.2 cm. What is its area? 13. A triangle has edges measuring 4.27 6.08 and 9.25 cm.
Give the diameter of the largest circle that can be fitted inside this triangle. 14. A rhombus has an edgelength of 6 cm and its shorter diagonal measures 3.8 cm.
Find its area. 15. A field is in the shape of a quadrilateral. Identifying its four vertices as ABCD gives
AB = 127 metres
BC = 206 metres
CD = 332 metres
AD = 94 metres
BD = 183 metres
