Question

Find the perimeter of a rectangle whose length is 300 cm and breadth is 2 m.

a. 12 m
10 m
11 m
14 m​

Answer 1

Perimeter = 10 m

Step-by-step explanation:

Given:

• Length of rectangle is 300 cm.
• Length of breadth is 2 m.

To Find:

• What is the Perimeter of rectangle ?

Solution: First of all convert the cm to m.

Since, 100 cm = 1 m

∴ 300 cm = 300/100 = 3 m

So now we have

• Length = 3 m and breadth = 2 m

As we know that

Perimeter of Rectangle = 2(Length + Breadth)

$\implies{\rm }$ Perimeter = 2(3 + 2)

$\implies{\rm }$ Perimeter = 2 × 5

$\implies{\rm }$ Perimeter = 10 m

Hence, the perimeter of rectanglee will be 10 m. (Option B is correct)

• Opposite sides of a rectangle are equal.

• Measure of each angle of rectangle is 90°.

• Area = (Length × Breadth) sq units.

• Length = Area/breadth or Breadth = area/length

• Diagonal = √l² + b² units.

Answer 2

Answer:

Perimeter of Rectangle = 2(Length + Breadth)

Perimeter = 2(3 + 2)

Perimeter = 2 × 5

Perimeter = 10 m

Hence, the perimeter of rectanglee will be 10 m.

10 m IS THE ANSWER
