Answer:
perimeters of the rectangle=p=46.014 metres
Step-by-step explanation:
Given that:
Length (l) = 21 m
Area of rectangle(A) = 42.15 meter-square
Width (w)=?
Required data:
Perimater of Rectangle=p=?
Calculation:
As we know that Area of rectangle=A=l*w
Putting the value we get
42.15 m(square)=(21 m)*w
or w=42.15/21
or w=2.007 m
Now to find perimters of rectangle we know that
p=2(l + w) metres
putting the values
p=2(21+2.007) metres
p=2(23.007) metres
p=46.014 metres
Answer:perimeter = 46.014 meters
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
The area of a rectangle is given as 42.15 square meters. The length of the rectangle is given as 21 meters. This means that the width of the rectangle would be
Width = area/length = 42.15/21 = 2.007meters.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
Perimeter = 2(21 + 2.007) = 23.007 × 2 = 46.014 meters
