# Heron's formula - math word problems - page 2

1. Triangle Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the triangle. a = 158 b = 185 c = 201
2. The farmer The farmer would like to first seed his small field. The required amount depends on the seed area. Field has a triangular shape. The farmer had fenced field, so he knows the lengths of the sides: 119, 111 and 90 meters. Find a suitable way to determine th
3. Sides ratio Calculate the circumference of a triangle with area 84 cm2 if a:b:c = 10:17:21
4. Find the area Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. A = 50°, b = 30 ft, c = 14 ft
5. Is right triangle or not If right triangle ABC, have sides a=13, b=11.5, c=22.5. Find area.
6. Sss triangle Calculate the area and heights in the triangle ABC by sides a = 8cm, b = 11cm, c = 12cm
7. One trapezium One trapezium has AB=24M, BC=36M, CD=80M, DA=80M long sides. Find the area.
