She installed a wateringsystem and uses about 6

per m2

, daily, in thegarden. How much waterdoes she use in thegarden each day?Area = (2x3)+(3x3)+(.3x3)

= 19,5 cm2Actual area = 19,5 x (2)2 m2

Usage = 6 x (19,5) x (2)2

= 468

Below is a diagram of a shed. The roofof

the shed needs to be waterproofedwith a

type of paint called DriBest.7m 3

5m

Calculate the surface area of theroof.

A = 2 x (7x35)

= 490 m2

A 5 tin of DriBest paintcovers 15m2 of roof. It costs

R185 per tin. What is thecost to paint the roof?

No = 490 /15 32,7

Need 33 tins

Cost = 33 xR185

= R6 105

The Mololos want to put a ceiling intothe

shed. The ceiling is parallel to the floorplan.An opening, 2m x 6m, must be left

so that they can get into the ceiling.2m

7m 35m

Calculate the total ceiling area.

A = (6 x 35) (2x6)= 198 m2

The quote for installing the ceiling isR57/m2. What is the cost of installation?

Cost = 198 x R57

= R11 286

The floor plan (not to scale) of a factoryis

shown in the diagram below. The grey

areais the site on which the factory stands.

Calculate the entirearea of the factory.

The stand is twice as longas it is wide. Calculate the

area of the site.

A = 6x5+8x9+12x28+19x1

= 742 m2

A = 50 x 100= 5 000 m2

What % of the site does the factory cover?

% =742

/5000 x 100 = 14,84 %

If the factory has a horizontal ceiling 3mabove the floor, what is the internal volumeof the factory.

V = 742 x 3= 2 226 m3

The floor in the Admin is

to be tiled. The tiles are30cm square. How manytiles will be needed?

Length = 900 /30 = 30 tiles

Breadth = 800 /30 26,7

27 tiles used in breadth

Total = 30 x 27

= 810 tiles
