Area = long side multiplied by short side
A = LS
(note: length of circumference = 2πr)
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.
Some years after the founder’s death, the Bugatti brand was all-but-dead in Milan. It was however, revived, and car production resumed — in France. The parent company is German: Volkswagen. The car is therefore thoroughly European in nature and culture.
The original idea was to make a production car that generated over a thousand horsepower… something of a holy grail for the motor car industry, and a design feat that many considered impossible. Read the rest of this entry »
Fourier looked at heat flowing through building materials, and his experimental results produced ideas such as thermal conductivity, resistance and the thermal transmission co-efficient or u-value. Read the rest of this entry »
In design work, there is a business side of things that depends on loans and investments. There is also a business side of things where people invest different amounts for different periods of time in helping you — and you might have to figure out their share of things in the future.
There is also the idea of inflation and cost of living — as you have to design to a cost, a budget, you have to sometimes predict the future costs involved.
This is a small introduction to the basics of compound interest, included here in the hope that it may help. Read the rest of this entry »
