Ah, an acre of land is a beautiful thing, friend! It measures about 63.6 meters in width and 63.6 meters in length. Just imagine all the happy little trees and bushes you could plant on that much space!
The basic SI (metric) unit for any kind of length or distance (length, width, height, etc...) is the metre (or meter if you're American). Other metric units for height are obtained using multiple-of-ten prefixes - for example, kilometres for thousands of metres, or centimetres for hundredths of metres.
If we express the shortest side as x, then the rectangle's length is 3x (as it is 3 times as long as its width).To find the area multiply the length and witdh together.x * 3x = 3x2The area of the rectangle would be 3x2.e.g if the width of the rectangle was 4, the area would be:3 x 42 = 48
