Question

what is the perimeter of rectangle

Answer 1

◼PERIMETER:- The perimeter is the distance around a closed plane figure

◼The Perimeter of rectangle

$2(l + b)$

◼The perimeter of rectangle is equal to sum of all sides.
Rectangle opposite sides are congruent. so we need to know only length and breath.

EXAMPLE:-
⏬⏬
Find the perimeter of a rectangular field of length 30 m and width 25 m.

Sol= P=2(l+b)
2(30+25)
2×55
110

Answer 2

Answer:

•The perimeter is the distance around a closed plane figure

•The Perimeter of rectangle

2x(l + b)

•The perimeter of rectangle is equal to sum of all sides.

•Rectangle opposite sides are congruent. so we need to know only length and breath.

example:length of a rectangle is 8 cm and breadth is 4 cm.what is the perimeter of the rectangle?

2xlength+breadth

2x8cm+4cm

2x12cm

24cm
