23 ft. + 4 ft. on left and right= 27ft.

20ft width + 4 ft. on left and right = 24 ft.

We want ridges on both sides bringing triangles

Lets find the area of 2 triangles then 2 trapezoids

Base=24

Height=6ft

24*6/2=72

Trapezoids

Find the median of the base line =27ft + a ridge of 15ft divide by 2 to get the median of the brown line

Median=27+15/2=21

Area of the trapezoid= height*median

Height=24/2=12ft

12ft*21=252

There are 2 trapezoid and triangles

So multiply each by 2 to get total

Total square footage 144+504=648

Divide total square footage by 100

648 roofing square root

648/100=6.48 squares

Divide this by the square root foot of the iron sheets you have decided to use. For this example, I may decide to go with corrugated iron sheets (3*8) ft.

Corrugated roof dimensions are normally 8ft * 10ft. it’s time to subtract off 50mm as the overlap distance in gutters. Making 7.8ft*10ft. multiply them together to get net surface area of a roof to be used excluding gutter waste overlaps. Total number of square foot for every iron sheet = 24 sq ft sq. ft for every iron sheet.

Lastly, number of roof is = our total roof surface are is 729 sq. ft of roof divide Total number of square foot for every iron sheet.

648/24 sq ft =27 corrugated sheets.
