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
The area of square is 100 cm2. Its side is
The side of a square is 12 m. Its perimeter is
If the area of a square is 64 cm2, then its perimeter is
If the area of a square is 2.25 m2, then its perimeter is
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 cm2. If the length of the sheet is 25 cm, what is its width?
The side of a square is 8 cm. Its area is
The area of a rectangle is 96 cm2. 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)
Perimeter of rectangle =40 cm
