Answer:
mark me as brainliest
Step-by-step explanation:
given,
the area of square is=5184m²
s×s=5184
s²=5184
s=√5184
s=72
according to problem,
l=2x
b=x
we know that,
perimeter of square=perimeter of rectangle
4s=2(l+b)
4×72=2(2x+x)
288=6x
x=288/6
x=48
from problem,
l=2x
=2×48
=96
b=x
=48
therefore length is 96
breadth is 48
area of rectangle = l × b
= 96 × 48
=4608 m²

Given:-
- Area of square field = 5184 m².
To Find:-
- Area of rectangle.
Formula to be used:-
- Perimeter of square = 4a
- Perimeter of rectangle = 2 (l + b)
Solution:-
- Let the side of square field as a.
Then,
- ⇒ a² = 5184 m²
- ⇒ a = √5184 m
- ⇒ a = 2 × 2 × 2 × 9 = 72 m
Now,
- Perimeter of square = 4a
- Perimeter of square = 4(72)
- Perimeter of square = 288 m
Now,
- Perimeter of rectangle = 2 (l + b)
- ⇒ 288 = 2 (l + b)
As length is twice of its breadth,
- ⇒ 288 = 2 × (2b + b)
- ⇒ 288 = 2 × 3b
- ⇒ 288/2 = 3b
- ⇒ 144 = 3b
- ⇒ 144/3 = b
- ⇒ b = 48
- Here, breadth is 48 m
Now length,
- Length = 2 × 48 = 96 m
Now, Area of rectangle
- Area of rectangle = l × b
- Area of rectangle = 96 × 48
- Area of rectangle = 4608 m².
✝ Hence, the Area of rectangle is 4608 m² ✝
