Multiply its length in metres by its width in metres.
Multiply the length by the width: 7 x 6 = 42. If the the units of length and width are metres (m) then the are would be metres squared (m2).
5 metres
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
30*1 = 30 square metres.
The perimeter is 42 metres.
Suppose width is x metres. Then length is x+5 metres. Now, perimeter = 2*(width + length) so 54 = 2*[x + (x+5)] = 2*(2x + 5) So 27 = 2x + 5 => 22 = 2x => x = 11 and so x+5 = 16. So the length and width are 16 and 11 metres, respectively.
if the length is 36 on a rectangle then what is the width of the rectangle
15 metres x 60 metres = 900 sq. metres.
The width and length of a rectangle are two of its main dimensions. The width is the measurement of the shorter side of the rectangle, while the length is the measurement of the longer side. The area of a rectangle is calculated by multiplying the width by the length.
To work out the area of a square or a rectangle, all you need to do is multiply the length by the width. In this case the room is the rectangle, and its length is 6 metres and its width is 4 metres. So its area is 6m x 4m = 24sqm.
Conventionally, length > width. With that assumption, if L is the length and W the width (both in metres) then 3.75 < L < 7.5 and W = 7.5 - L If L = 3.75 then W = L and the rectangle becomes a square.
