2009-01-22

We did a trial post called “Data on Living Room Armchairs and Sofas” some years ago (along with other “test posts”.  the idea being that if it achieved a certain number of hits then we would generate more articles of that ilk.

We recently have noticed that his post has met the target — so this is the “follow up”.  It is about layouts of living rooms. Read the rest of this entry »

## Areas of Geometric Figures

### Rectangle:

Area = long side multiplied by short side

A = LS

A=bh

### Circle:

A=π

(note: length of circumference = 2πr)

Area

= (ah)/2

=(a/2)h

=(bc sinA)/2

### Square Metre or Metre Squared:

Is four squared metres the same as four metres squared?

No, and the difference is vast, so care must be taken.

The best way is to remember that m² is always said aloud as “square metres” and never, ever as “metres square”. Some people prefer to write sq.m to help them remember.

Four metres square is sixteen square metres:

A square with sides equal to 4m — gives an area of 4m by 4m or 16m². (16 sqm). Think of this as saying four metres all squared — square the 4 and square the m — which is 4 x 4 x m x m = 16m².

Four square metres is two metres square:

A square with sides equal to 2m — gives an area of 2m by 2m or 4m² (4 sqm). Think of this as saying two metres all squared — square the 2 and square the m — which is 2 x 2 x m x m = 4m².

Two square metres:

A rectangle of sides 1m by 2m, produces an area of 2m²(2 sqm), and NOT two metres square.
