Question

the perimeter and area of a rectangular play ground are 80m and 384m2 respectively find the length and breadth of the play ground​

Answer 1

Answer:

Area of playground = \length × breath =80×35=280m2

⇒ Total cost =Rs. 2800×45=Rs. 12600

Perimeter of playground =2(length+breath)=2(80+35)

                                                                                 =(2(115)=230m

⇒times=speeddistance=1.5230=153.33sec.

Answer 2

Step-by-step explanation:

Hi Jannat kesi ho friend

Perimeter = 80

Area = 384

l and b find out

2(l+b)=80

l+b=40

lb= 384

l= (√40²-4(384) + 40/2

l = (√64+40/2)

l= 8+40/2

l=24

l+b=40

24+b=40

b=16
