Our lovers Bessie and John have escaped they caught the boat to scotland and a marriage together, now we turn back, we cross over to Baltic Square...but wait look at the Tyne Bridge.
Using the squares and triangles drawn on the picture below, calculate the approximate area enclosed between the arc of the bridge and the road. Count a square as one unit 2 and a triangle as a half unit 2 .
b) Using one unit 2 as equal to 15m 2 , recalculate your result from (a) in m 2
c) How could you improve this approximate calculation?
