Question

A, rectangular playing ground is25m long and 15m board A path of 3m width is all around inside it along border find the area of path​

Answer 1

Area of rectangle = l × b

= 25 m × 15 m

= 375 m sq.

Area of path = Area of rectangle + width of path

= 375 m sq. + 15 m

Answer 2

Step-by-step explanation:

Understandingthequestion

➨ This question says that the rectangular playground has length as 25 metres and 15 metres as breadth. A path of 3 metres width ( breadth ) is all around inside it along the border. We have to find the area of that path.

{\large{\bold{\sf{\underline{Given \; that}}}}}

Giventhat

➨ Length of rectangular playground = 25 metres.

➨ Breadth of rectangular playground = 15 metres.

➨ Path of 3 metres in breadth is all around inside it along the border.

FullSolution

~ Let us find area of that rectangular playground firstly'

➸ Area of rectangular playground = Length × Breadth

➸ Area of rectangular playground = (25 × 15) metres

➸ Area of rectangular playground = 375 m²

~ Now let's find area of that playground including border and inside area

➸ Length = ( 25 + 3 + 3 ) m = 31 m

➸ Breadth = ( 15 + 3 + 3 ) m = 21 m

➸ Area = Length × Breadth

➸ Area of = ( 31 × 21 ) metres

➸ Area = 651 m²

~ Now at last let us find area of path

➸ Area of path = Area of playground including border and inside area - rectangular playground area

➸ Area of path = ( 651 - 375 ) m²

➸ Area of path = 276 m²
