Question

A rectangular sheet is of length 2.4m and breadth 80cm find the ratio of breadth to
length .Also find the ratio of breadth to its perimeter.

Answer 1

Answer:

•Ratio of breadth to length = 1:3

•Ratio of breadth to its perimeter = 1:8

Step-by-step explanation:

Given:

• Length of the rectangular sheet = 2.4 m = 240 cm
• Breadth of the rectangular sheet = 80 cm

To find:

• Ratio of breadth to length.
• Ratio of breadth to perimeter.

Solution:

• Breadth (b) = 240 cm
• Length (l) = 80 cm

Ratio of breadth to length,

= Breadth : Length

= 80 : 240

= 1 : 3

We know that,

${\boxed{\sf{Perimeter\:of\: rectangle=2(length+breadth)}}}$

Perimeter of rectangular sheet,

= 2(240+80) cm

= 2× 320 cm

= 640 cm

Ratio of breadth to perimeter,

= Breadth : Perimeter

= 80 : 640

= 1 : 8

• Area of rectangle = length× breath
• Diagonal of rectangle = √(length ²+breadth ²)
• Perimeter of square = 4× side
• Area of square = side²

Answer 2

Answer:

$\huge \bf \: solution$

$\small \rm \underline {firstly \: lets \: understand \: the \: concept}$

There is a rectangular sheet which has length as 2.4 m

and breadth as 80 cm And we have to find its ratio of Breadth to length and breadth to perimeter.

Q1

$\rm \: length \: = 2.4 \: m$

$\rm \: breadth \: = 80 \: cm$

$\sf \: we \: have \: to \: convert \: into \: like \: terms$

$\rm \: 1 \: m \: = 100cm \: \ \\ \rm \: 2.4 \: m \: = 2 \times 100 + 40 = 240 \: cm$

Now, finding ratio .

$\: \rm \: breadth \ratio \: length \: = 80 \ratio \: 240 = 1 \ratio3$

Q2

For finding ratio we have to first find its perimeter

$\huge \bf \: perimeter \: = 2(l + b)$

$\rm \: perimeter \: = 2(240 + 80)$

$\rm \: perimeter \: = 2(320)$

$\rm \: perimeter \: = 640 \: cm$

Now finding ratio.

$\rm \: breadth \ratio \: perimeter \: = 80\ratio640 = 1\ratio8$
