Question

A bridge is covered with triangular panels to keep the kids from looking down and getting scared. If there are seven panels on each side (length of 1.7 meters) of the bridge, find the total area to cover the bridge. (Round to the nearest meter)

Answer 1

Answer:

Total area to cover the bridge = 17.52 m²≅

Step-by-step explanation:

The triangular panels are equilateral triangles

Area of equilateral triangles = A= (√3/4)a² where a= 1.7 meters

Since there are 14 panes Area = 14 x  (√3/4)a² = 14 x  (√3/4)1.7² = 17.52 m²≅
