Question

5) The perimeter of a rectangular park is 100cm. If the length of the park is

40cm, then find its breadth.​

Answer 1

Step-by-step explanation:

Heya!!

Here is your answer!!

Length of the park = 40 cm.

Perimeter of a rectangle = 100 cm.

$2(l + b) = 100$

$l + b = 50$

$40 + b = 50$

$b = 50 - 40$

$breadth \: = 50 - 40 = 10cm.$

Hope it helps you!!

Answer 2

Answer:

Question :-

• The perimeter of a rectangular park is 100cm. If the length of the park is 40cm, then find its breadth.

Given :-

• Perimeter of a rectangular park is 100 cm.
• Length of the park is 40 cm.

Find out :-

• Breadth of a rectangular park.

Solution :-

We know that,

◘ Perimeter = 2( length + breadth )

Then,

➠ 100 = 2( 40 + breadth )

➠ 100/2 = 40 + breadth

➠ 50 = 40 + breadth

➠ 50 - 40 = breadth

➠ 10 = breadth

➠ Breadth = 10 cm

∴ Breadth of a rectangular park 10 cm.
