Rechthoek

Om de oppervlakte van een rechthoek te berekenen moet je de lengte van de rechthoek vermenigvuldigen met de breedte van de rechthoek. De formule voor de oppervlakte van een rechthoek is:

A=l\cdot bA=l\cdotA=lA=, waarin:

•A=\text{ oppervlakte}A=\text{ oppervlakt}A=\text{ oppervlak}A=\text{ oppervla}A=\text{ oppervlaj}A=\text{ oppervlajk}A=\text{ oppervlajk}A=\text{ oppervla}A=\text{ oppervl}A=\text{ opperv}A=\text{ opper}A=\text{ oppe}A=\text{ opp}A=\text{ op}A=\text{ o}A=\text{ }A=\text{ l}A=\text{ lengte}A=\text{ lengte}A=\text{lengte}A=A=A=A=A=A=A=A=A=A=A=A=A=lA=leA=lenA=len>A=len>eA=len>A=lengA=lenA=leA=l

•l=\text{ lengte}l=\text{ lengte}l=\text{lengte}=\text{lengte}A=\text{lengte}A=A=A=

•b=\text{ breedte}=\text{ breedte}A=\text{ breedte}A=\text{ breedtelengte}A=\text{ breedtlengte}A=\text{ breedlengte}A=\text{ breelengte}A=\text{ brelengte}A=\text{ brlengte}A=\text{ blengte}A=\text{ lengte}A=\text{ lengte}A=\text{lengte}A=

Stel, we hebben een rechthoek getekend en willen de oppervlakte ervan weten. De lengte ervan meten we met een geodriehoek en vinden dat deze5\operatorname{cm}5c55cis. Hierna meten we de breedte die4\operatorname{cm}4cblijkt te zijn. Deze formule invullen geeft5\cdot4=20\operatorname{cm}^25\cdot4=20\operatorname{cm}5\cdot4=20c5\cdot4=205\cdot4=20c5\cdot4=20cm5\cdot4=20cm^5\cdot4=20cm^{2}5\cdot=20cm^{2}. Dus de oppervlakte isvierkante centimeter.

Omrekenen van oppervlakte-eenheden

Nu we hebben bepaald dat de oppervlakte van onze rechthoekvierkante centimeter is, gaan we dit omrekenen naar een andere oppervlakte-eenheid, namelijk vierkante millimeter. Met behulp van onze geodriehoek ontdekken we dat de lengte van de rechthoek50\operatorname{mm}50m(millimeter) is en de breedte40\operatorname{mm}40m. De oppervlakte van de rechthoek in vierkante millimeters wordt dan50\cdot40=2000\operatorname{mm}^250\cdot40=2000\operatorname{mm}50\cdot40=2000m50\cdot40=2000mm^{2}50\cdot4=2000mm^{2}50\cdot=2000mm^{2}. Dus de oppervlakte van onze rechthoek is20\operatorname{cm}^220\operatorname{cm}20cen ook2000\operatorname{mm}^22000\operatorname{mm}2000m.

Rekenregel

De algemene regel is: elke stap naar links is vermenigvuldigen met 100, elke stap naar rechts is delen door 100.

Onthoud ook dat een vierkante decameter\left(\operatorname{dam}^2\right)\left(\operatorname{cdam}^2\right)\left(\operatorname{cdam}^2d\right)\left(\operatorname{cdam}^2da\right)\left(\operatorname{cdam}^2dam\right)\left(\operatorname{cdam}^2dam2\right)\left(\operatorname{cdam}dam2\right)\left(\operatorname{cdm}dam2\right)\left(\operatorname{cm}dam2\right)\left(cdam2\right)\left(dam2\right)ook wel een are wordt genoemd en een vierkante hectometer\left(\operatorname{hm}^2\right)\left(\operatorname{hm}^2h\right)\left(\operatorname{hm}^2hm\right)\left(\operatorname{hm}^2hm2\right)\left(\operatorname{chm}^2hm2\right)\left(\operatorname{cm}^2hm2\right)\left(\operatorname{cm}^2hm2\right)\left(\operatorname{hcm}^2hm2\right)\left(\operatorname{hm}^2hm2\right)\left(\operatorname{m}^2hm2\right)\left(\operatorname{cm}^2hm2\right)\left(\operatorname{cm}hm2\right)\left(chm2\right)\left(hm2\right)ook wel een hectare (ha) wordt genoemd.
