Answer 1

Answer:

I hope the answer helps you

Answer 2

Given :

• Side of a square = 5 cm

• Length of a rectangle = 4 cm

• Breadth of a rectangle = 5 cm

To find :

Which has greater perimeter rectangle or square?

Solution :

Calculating the perimeter of square :-

Using formula,

Perimeter of sqaure = 4a

where,

a denotes the side of square

Substituting the given values :-

→ Perimeter of square = 4 × 5

→ Perimeter of square = 20

Therefore, the perimeter of square = 20 cm

Now, calculating the perimeter of rectangle :-

Using formula,

Perimeter of rectangle = 2(l + b)

where,

l denotes the length of the rectangle

b denotes the breadth of the rectangle

Substituting the given values :-

→ Perimeter of rectangle = 2(4 + 5)

→ Periemter of rectangle = 2(9)

→ Perimeter of rectangle = 18

Therefore, the perimeter of rectangle = 18 cm

Perimeter of sqaure > Perimeter of rectangle

The perimeter of square is greater than the perimeter of rectangle by 2 cm.
