The answer is 12 cm.
21cm3
Perimeter of a rectangle = 2*(Length + Breadth) = 2*(2.5 + 1.5) = 2*4 = 8 cm
The area of rectangle is : 100.0
28 cm
The width of the rectangle is 4 cm
It equals 18. Add the sides together.
6cm. The perimeter of the rectangle has to add to 20. 4+4+6+6=20 Hope this helps ;-)
6x4 has a perimeter of 2*(6+4) = 2*10 = 20 cm 6.5x2 has a perimeter of 2*(6.5+2) = 2*8.5 = 17 cm So the first has the larger perimeter.
40 meters.
Anything greater than 27.713cm (4 x √48).
The perimeter of the rectangle is the sum of its 4 sides.
