Answer 1

Answer:

Step-by-step explanation:

1

i) Land occupies by the park is 40*30=1200m²

ii) Area of the path to be cemented if 1m is the width of the path

=(40*1)+(29*1)+(39*1)+(28*1)

=40+29+39+28

=136m²

iii) Area of the park left after cementing the path= Area of the park- area of the path

required=1200-136

=1064m²

Answer 2

Total length of the fence is 140m

Total land occupied by park is 1200m²

Area of path to be cemented is 136m²

Area of park left after cementing is 1064m²

• length of fence = perimeter

• perimeter = 2(L+B)

= 2(40+30)

= 2(70)

= 140m

• Total area of park = LxB

= 40×30

= 1200 m²

• Area of path to be cemented with width 1 m = 40×1+30×1+40×1+30×1-4

= 40 + 30 + 40 + 30 - 4

= 136 m²

• Area of park left after cementing = 1200-136=1064m²
