Question

rectangular field of 150 m by 100 m has a 10 m path around it. Find the area of the path.
​

Answer 1

Answer:

$5400 {m}^{2}$

Step-by-step explanation:

$area \: of \: small \: rectangle = l \times b \\ = 150 \times 100 \\ = 15000 {m}^{2} \\ area \: of \: big \: rectangle = 170 \times 120 \\ = 20400 {m}^{2} \\ area \: of \: path \: = area \: of \: big \: rectangle \: - area \: of \: small \: rectangle \\ = 20400 {m}^{2} - 15000 {m}^{2} \\ = 5400 {m}^{2}$
