Question

A path of 2 m wide is built along the border and inside a square garden of side 60 m find: (a) the area of path (b) the cost of cultivating flowers in the remaining portion of the garden at the rate of $ 5 per m2

Answer 1

Step-by-step explanation:

area of path = area of outer square(60*60)–area of inner square(56*56) area of path= 3600–3136. area of path=564 sqm

Answer 2

Answer:

a) 464 m2  

b) Rs.15680

Step-by-step explanation:

Area of ABCD =AB × BC= 60 x 60 m2 = 3600 m2

PO =QR=RS=SP=60-2-2 = 56 m

Area of PQRS = PQ × OR

=56 × 56 = 3136 m2

(a)Area of path =area of ABCD - area of PORS

=3600 -3136 = 464 m2

(b) Cost of cultivating flowers = Rs.3136 × 5 = Rs.15680
