Question

A rectangular field measures 400m by 550m. What is the perimeter of the field?
a. in meters b. in kilometers
Please show solving.

Answer 1

Answer:

a. 1900 metres. b. 1.9 Kilometers

Step-by-step explanation:

2 × (400+550) = 2 × (950) = 1900 metres

= 1900 ÷ 1000 = 1.9 Kilometers

Answer 2

Given

• Length = 550m
• Breadth = 400m

To Find

• Perimeter in meters and kilometres

Solution

____________________

We know that

${\sf Perimeter = 2(length+breadth)}$

${\sf Perimeter \: _{\bf{(In~~Meters)}}= 2(550m + 400m)}$

${\sf Perimeter \: _{\bf{(In~~Meters)}}= 2 \times 950m}$

${\sf Perimeter \: _{\bf{(In~~Meters)}}= 1900m}$

${\sf Perimeter ~ \: \: _{\bf{(In~~killometers)}}= \ \dfrac{1900km}{1000 }}$

${\sf Perimeter \: \: _{\bf{(In~~killometers)}}= 1.9km}$
