Question

3. A rectangular park is 90 m long and 70 m broad. A
path 6 m wide is to be built around the inside of the
park. Find the area of the path. Also
of the remaining park in hectares.​

Answer 1

Answer:

Area of path=0.1776 hectares

Area of remaining park=0.4524 hectares

Step-by-step explanation:

$area \: of \: the \: rectangle = l \times b \\ = 90 \times 70 \\ = 6300 {m}^{2} \\ area \: of remaining \: park = 78 \times 58 \\ = 4524 {m}^{2} \\ = \frac{4524}{10000} \\ = 0.4524 \: hectares\\ area \: of \: path \: = 6300 - 4524 = 1776 {m}^{2} \\ = \frac{1776}{10000} \\ = 0.1776 \: hectares$
