The length and breadth of a rectangle are 40 cm and 10 cm respectively. Its perimeter is
We know, Perimeter of a rectangle is 2 ( l + b )
Here Length (l) = 40 cm and Breadth (b) = 10 cm
So putting the values in the above equation we have :
2 ( 40 + 10 ) = 2(50) = 100 cm
So perimeter of a rectangle is 100 cm.
The length of a rectangle is 150 cm. If its breadth is 1 m, then its perimeter is
Length of rectangle=150 cm = 1.5 m
breadth of rectangle=1 m
perimeter=2(length+breadth)
=2(1.5+1)
=2×2.5
=5.0 m
Perimeter of square is 4 X side
thus 4 X 12 = 48 m
The side of a square is 6 cm. If its side is doubled, then its new perimeter is
The area of a rectangular sheet is 500 cm^{2}. If the length of the sheet is 25 cm, what is its width?
The area of a rectangle is 96 cm^{2}. If the breadth of the rectangle is 8 cm, find its perimeter.
Area of rectangle = L×B
_{96 = L×8}
L = 96/8
Length of rectangle = 12cm
Perimeter of rectangle = 2×(l+b)
= 2× (12+8)
= 2×20
Perimeter of rectangle =40 cm
