Question

2. A 3 m wide path runs outside and around a rectangular park of length 125 m and
breadth 65 m. Find the area of the path.
3. A picture is painted on a cardboard 8 cm long and 5 cm wide such that there is a
margin of 1.5 cm along each of its sides. Find the total area of the margin.​

Answer 1

Answer:

2 . Area of rectangular park = length × breadth

$= (125 × 65) m^2$

$= 8125 m^2$

Since 3m wide path runs outside the park .So the length of park along with

path is 131m and the breadth of park

along with park is 71.

Area of park with path = 131×71

$= 9301m^2$

Area of path = area of rectangular park with path - area of park

$= (9301-8125)m^2$

$= 1176 m^2$
