Question

A park is 22m long and 20m wide. grass is planted in a rectangular region of the park with an area to 230 sq. m. find the area of the region where the grass is not planted.​

Answer 1

Answer:

Given

Length of the park = 50 m

Breadth of the park = 30 m

Area of the park = 50×30

=1500m

2

Width of the path inside the park = 2m

Length of the park without path = 50−(2+2)=50−4=46m

Breadth of the park without path = 30−(2+2)=30−4=26m

Area of the park without the path = 46×26

=1196m

2

Area of the path = Area of park - Area of park without path

=1500−1196

=304m

Answer 2

Answer:

Answer is 210 sq.m

Step by step explanation:

Step-1

Length of the park= 22m

Breadth of the park=20m

∴Area of the park=LxB

=(22x20)m

=440 sq.m

Step-2

Area of the park where grass is planted=230 sq.m

∴Area of the park where grass is not planted= Area of

the park - Rea of the

region where grass is planted

=440 sq.m-230 sq.m

=210 sq.m
