What is the surface area of this design?

The surface area of given design is 197 in².

Step-by-step explanation:

All the phases expect the side phases are rectangles.

The area of rectangle = Length × Breadth.

Top phase area = 5 × 5=25 in.

Bottom phase area = 9 × 5=45in.

Left Phase area = 5 × 5 =25in.

Right Phase area = 6.4 × 5=32in.

Side phases are of equal area and of the shape quadrilateral.

Area of quadrilateral given = Area of rectangle + Area of triangle

= 5 × 5  + (1/2) × 4 × 5

= 35 in.

Total Surface area = Top phase area + Bottom phase area + Left Phase area + Right Phase area + 2×( Side Phase Area)

                               = 25+45+25+32+(2×35)

                               = 197 in².

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
