The mural Northern Tradition and Transition, located in the Saskatchewan Legislature, was painted by Métis artist Roger Jerome to honour the province of Saskatchewan’s 100th anniversary in 2005. The mural includes a parabolic arch. The approximate shape of the arch can be modelled by the function h(d) = -0.4(d - 2.5)2 + 2.5, where h is the height of the arch, in metres, and d is the distance, in metres, from one end of the arch. How wide is the arch at its base?
