Given - Length of the Rectangular Plot : 16 meters
Given - Width of the Rectangular Plot : 4 meters
We know that - Area of a Rectangle is given by : Length × Width
Area of the Rectangular plot = (16 × 4) m²
Area of the Rectangular plot = 64 m²
Given : Square plot and Rectangular plot have same Area
Area of Rectangular plot = Area of Square plot
Area of Square plot = 64 m²
We know that - Area of Square is given by : Side × Side
Side × Side = 64 m²
S² = 64 m²
S² = 8² m²
S = 8 m
<u>Answer</u> : One side of the Square Garden plot is 8 meter
Answer:
1)b
2)d)80/360×36π≈25.12cm²
4)d)32.5
5)c)135°
6)d)4π/3
Step-by-step explanation:
1) because as we know
Circle equation
=(x-a)²+(y-b)²=r²
=(x-5)²+(y+1)²=36 (given)
=(x-(+5))²+(y-(-1))²=6²
So
C(5,-1)and r=6
2)as we know area of sector
=Theta/360×πr²
=80/360×6²π
80/360×36×3.14
80/10×3.14
=25.12
4)to figure out 4 we have to separate the shape into 2 parts
First semi-circul
Second rectangle
So the parameter of the shape
=Circumference of semi-circul + the parameter of the rectangle
=[10π×½+2(10+3.4)]-10 (as the dashed line is not a part of parameter)
=[15.7+26.8]-10
=32.5
5)3π/4
3×180/4
540/4
135
6)240°
240°×π/180°
4π/3
