Question

5. Shivani has a rectangular garden of length 22 m and breadth 15 m. Her friend Rishi
has a square garden of side 21 m. Whose garden is bigger and by how much?​

Answer 1

Answer:

Answer: Rishi's garden is bigger by 111sq.m

Step-by-step explanation:

To find if it is bigger we have to find the area

Area of a rectangle (formula) = length × breadth

Area of Shivani's garden = 22m×15m

=330sq.m

Area of a square (formula)= side×side

Area of Rishi's garden = 21m×21m

=441sq.m

So Rishi's garden is big but to find how big it is we have to subtract the area of Shivani's garden from Rishi's garden

= 441sq.m-330sq.m

=111sq.m

Answer 2

Answer:

Rishi's garden is bigger and by 10m more

Step-by-step explanation:

Rectangular garden of Shivani = length 22m ; breadth 15m

Square garden of Rishi = Side 21m

We need to find its perimeter,

Perimeter of rectangle = 2 ( l + b )

                                      = 2 ( 22 + 15 )

                                      = 2 x 37

                                      = 74

Perimeter of square     = 4a

                                      = 4 x 21

                                      = 84

We need to compare the following perimeter,

Perimeter of square is bigger than rectangle.

So, Rishi's garden is bigger.

Now we need to find by how much?

So we will subtract perimeter of rishi and Shivani.

84-74=10
