Question

How many rectangles can you make with a perimeter of 12 sq. cm.? Find the area of each
A playground has length 230 m and breadth 415 m. What is the perimeter and area of​

Answer 1

Answer:

perimeter - 645 formula sum of all sides

Answer 2

step by step explanation

Assuming all length are integers, the dimensions would be pairs of integers with a sum of 6 , since

Perimeter=2( Length+Width)

There are 3 distinct rectangles that meet the 12 cm perimeter requirements.

The dimensions,in cm ,are

1 and 5

2 and 4

3 and 3

*Note:A square is a rectangle having all sides and all angles equal.

Area= length× width

5 cm square

8 cm square

9 cm square

length of the playground= 230 m

breadth of a playground= 415 m

As,we know

Area of a rectangle=L×B

= 230 m×415 m

=95,450 m

And Perimeter= 2( L+B)

=2(230+415)

=460+830

=1,290 m

So ,Area = 95,450 m

and Perimeter= 1,290m
