Question

Which measure is the best estimate of the area of the banner in square meters? Can you show me how to do it ?

Answer 1

For the middle sections, you can use the area of a trapezoid: 1/2(h1+h2)b

1/2(1.25+2)1=1.625

The two triangles can form a square

1.25*1.75=2.1875

Add it all together
1.625+1.625+2.1875=5.4375
