Answer 1

Answer:

Question -

*Length of a rectangle is 5cm and breadth is 3 cm then find the ratio of its perimeter to it's area.*

‎ ‎

‎ ‎

Given-

Length=5cm

Breadth= 3cm

‎ ‎

‎ ‎

To find -

↬Perimeter

↬Area

↬The ratio of the obtained Perimeter and area.

‎ ‎

‎ ‎

Solution-

➼Let first find the perimeter with the given dimensions.

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

2(5+3)

= 2×8

= 16cm

‎ ‎

➼Now, let's find the area.

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

$5 \times 3 \\ = {15cm}^{2}$

‎ ‎

➼After obtaining the perimeter (16cm) and area($\bold{15cm}^{2}$), let's now find the ratio of them.

16:15

= 16:15

‎ ‎

‎ ‎

Required Answer -

$\rightarrow$The ratio of the given Perimeter and area = 16:15

So, correct option-

‎ ‎‎ ‎‎ ‎‎ ‎‎ ‎‎ ‎2️⃣ 16:15

Answer 2

$\pink \bigstar$Question:-,$\pink \bigstar$

Length Of a rectangle is 5cm and breadth is 3 cm then Find the ratio of its Perimeter to it's area.

1). 8:15

2). 16:15

3). 15:16

4). 15:8

$\pink \bigstar$Given:-$\pink \bigstar$

Length = 5cm

Breadth = 3cm

$\pink \bigstar$To Find:-$\pink \bigstar$

Perimeter to it's area.

So,let's Find perimeter.

Perimeter = 2[length + Breadth]

$\pink {\sf{2(5 + 3)}}$

$\pink{ \sf{2 \times 8}}$

$\pink {\sf{16 \: cm}}$

Now,let's Find the Area.

Area = length × Breadth

$\pink {\sf{5 \times 3}}$

$\pink{ \sf{15 \: c {m}^{2}}}$

$\pink \bigstar$Answer:-$\pink \bigstar$

So,16:15 is Correct option.
