Step-by-step explanation:
2) The total length of tape required = Perimeter of the rectangle
= 2(lenght+breadth)
= 2(40+10)
= 2(50)
= 100 cmn
= 1 meter
Therefore, total length of tape required is 100 cm or 1 meter.
3) The perimeter of table = Perimeter of a rectangle
= 2(length + breadth)
= 2(225+150)
= 2(375)
= 750 cm
= 7 m 50 cm
Perimeter of table is 7m 50cm.
4)the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively is 106 cm.
5)The perimeter of a rectangular piece of land = 2(Length + Breadth)
= 2(0.7+0.5)
= 2(1.2)
= 2.4 km
\because1km\ =\ 1000m∵1km = 1000m
\therefore0.24\ =\ 1000\times0.24=2400∴0.24 = 1000×0.24=2400 m.
Since 4 rows of wire is required.
\therefore2400\times4=9600∴2400×4=9600 m.
\therefore9600\ m\ =\ 9.6\ km∴9600 m = 9.6 km
Therefore, length of wire required is 9.6 km or 9600 m.
