30 cm. Find i)The area of the path.
ii) The cost of the planting grass in the remaining portion of the garden at the
rate of Rs 40 per m²​

Answer 1

side of outer square = 30 cm

side of inner square = 30 - 1 - 1 = 28 cm

area of outer square =30*30=900cm²

area of inner square =28*28= 784cm²

area of path = area of outer square - area of inner square

area of path =900-784=116cm²
