Question

What is the perimeter of a rectangle whose length is 1.3 km and breadth is 800m

Answer 1

Perimeter of a rectangle = 2(L+B)

Length 1.3 Km =1300 m
Breadth= 800 m

= 2(1300+800)
=2(2100)
=4200 m

Answer 2

Answer ⇒

Step-by-step explanation ⇒ Given condition,

Length = 1.3 km = 1300 m.

Breadth = 800 m.

Now, Perimeter is the sum of the length of the boundary of any geometrical figure.

∴ For Rectangle of length L and Breadth B,

Perimeter = L + L + B + B

∴ Perimeter = 2(L + B)

∴ Perimeter = 2(1300 + 800)

∴ Perimeter = 2 × 2100

∴ Perimeter of the Rectangular Field = 4200 m = 4.2 km.

Hope it helps.
