Answer 1

Answer:

length = longest side= 4cm

breadth =short(fat)side= 3cm

So,

Perimeter of rectangle= 2×(length+breadth)

= 2×(3+4) cm

= 14 cm ans.

The way formula is derived:

perimeter= side1+side2+side3+side4

= length+breadth+length+breadth

= 2length+ 2breadth

= 2 (length+breadth)

Answer 2

Perimeter of a rectangle=2(Length+Breadth)

=2(4cm+3cm)

=2(7cm)

=14cm
