Question

Ria has a field with a flowerbed and grassland. The grassland is in the shape of a rectangle, while the flowerbed is in the shape of a square. The length of the grassland is found to be 3 meters more than twice the length of the flowerbed. The total area of the whole land is 1260 mt sq. Now Questions:

Answer 1

Step-by-step explanation:

Given that,

Length of rectangular lawn =10 m

Width of rectangular lawn =5 m

and

radius of flower bed =2 m

Part (1):

The area of whole land = Area of rectangular lawn

=length×width

=10×5=50 m

2

The area of whole land =50 m

2

Part (2):

Area of flower bed = Area of circle

=πr

2

=3.14×2

2

×=12.56 m

2

Area of flower bed =12.56 m

2

Part (3):

The area of lawn excluding the area of the flower bed

= rectangular lawn − Area of circle

=50−12.56

=37.44 m

2

The area of lawn excluding the area of flower bed =37.44 m

2

Part (4):

Circumference of the flower bed = circumference of circle =2πr

=2×3.14×2=12.56 m

Circumference of the flower bed =12.56 m
