Answer:
261 cm²
Step-by-step explanation:
The area of the hexagon is 6 times the area of one of the triangles. The area of a triangle is base × height ÷ 2.
A = 6(8.7)10 ÷ 2
A = 261 cm²
A regular hexagon is made up of six triangles having a height of 8.7cm and a base of 10cm. So the area of the hexagon is 6 times the area of one of the triangles. Since the area of a triangle is bh/2 we have
A=6(8.7)10/2
A=261cm^2
