The actual dimensions of the TV (vs. the screen) will depend upon the width of the frame surrounding the screen. Some variable include the location of the speakers as some units have the speakers on the side of the panel and others have the speakers below the screen.
Rectangular perimeter = 2(Length + Width) Width = a Length = a+5 Then, 84 = 2(a+a+5) 42 = 2a+5 (42-5)/2 = a = 18.5m = Width Length = a+5 = 23.5m
A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.
42
Height 42 mtrs
None. 42 yards is a length with no width. Therefore it cannot have a perimeter.
The width is 24 feet.
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).
Let w be the width, then 2(7 + w) = 42 or 14 + 2w = 42 or 2w = 42 - 14 or 2w = 28 w = 14
2 (x + 2x) = 42 x + 2x = 21 3x = 21 Therefore, x = 7 The width of the rectangle is 7 inches. The length of the rectangle is 14 inches.
Perimeter = width*2 + length *2 112 = 14 * 2 + length * 2 56 = 14 + length length = 56 - 14= 42
Let the length be 2x+3 and the width be x: So: 2*(2x+3+x) = 258 => x = 42 feet Therefore: length = 87 feet and width = 42 feet Check: 2*(87+42) = 256 feet
The width is 5.557 feet to 3 decimal places and its length is 7.557 feet to 3 decimal places
