Answer 1

Step-by-step explanation:

Given,

• Length of rectangular garden = 80 m
• Breadth of rectangular garden = 40 m
• Width of crossing path 2.5 m

Now ,

$\boxed{ \bf \red{Area \: of \: length \: wise \: path \: = 80 × 2.5 = 200 m^2}}$

$\boxed{ \bf \purple{Area \: of \: breadth \: wise \: path \: = 40 × 2.5 = 100 m^2}}$

(i) Total area of both paths

$\bf= 200 + 100 – 2.5 × 2.5 m^2 \\ \bf= 300 – 6.25 = 293.75 m^2$

(ii) Area of an unshaded portion

= Area of the garden – Area of paths

$\bf= 80 × 40 – 293.75 m^2 \\ \bf = 3200 – 293.75 m^2 \\ \bf = 2906.25 m^2$

Thanks :-)
