Find the area of square park whose perimeter is 320 m

OR

The perimeter of rectangle is 100cm, if the length is 35cm find breath and area of rectangle

$\boxed {\fcolorbox{white}{pink}{Answer}}$

1) Given : Perimeter of square = 320 m

We know that

Perimeter of square =4×side

320=4 × side

320/4= side

80 m = side

So,area of park = side ²

= 80²

= 6400 m ²

Or

2)

Given : perimeter of rectangle = 100 cm

Length of rectangle = 35 cm

We know that ,

perimeter of rectangle =2(l+b)

100=2(35+ breadth )

50=35 + breadth

50-35= breadth

15 = breadth

So, area of rectangle = l× b

= 35 ×15

= 525 cm ²

Answer 2

Answer:

Q1. solution

perimeter of square =4×side

320 =4 ×side

side =320/4

side =80 m

so area of square =side×side

=80×80

= 6400 m^2

Q2

perimeter of rectangle 2(l+b)

=100 =2(35+b)

=100/2 = 35+b

50=35+b

. b=50-35.

b=15

Now the area of rectangle = l×b

35×15=525

area of rectangle =525

hence

the breath of rectangle =15

and the area of rectangle = 525
