Two different perspectives of the triangle, D and E.
Answer:
the width and diameter are the same because all such pairs of parallel tangent lines have the same distance.
Step-by-step explanation:
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. ... For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all such pairs of parallel tangent lines have the same distance.
Divide the figure into known figures like rectangle and semi-circle
Calculate the area of the whole figure by adding the area of the separate figures
