Question

Area of rectangular field is3584 and length and bredth are in the ratio 7:2 resp.What is perimeter of rectangle

Answer 1

Answer:

Answer is 4608

Step-by-step explanation:

area of rectangle=length×breadth

area of rectangular field=3584

let the length and breadth be 7a and 2a

7a × 2a =3584

14a = 3584

a=3584/14

a=256

length=7×256=1792

breadth=2×256=512

perimeter of rectangle =2(l+b)

=2(1792+512)

=2×2304

=4608

I hope it will help u..

Answer 2

Answer:

268(m or c.m) (In this question there should be a measurement unit like m or c.m )

Step-by-step explanation:

Area of rectangle field=3584 (m² or c.m²)

length:breadth=7:2

Let length be 7x and breadth=2x

Rectangular area=l×b (As we know rectangle area formula=l×b)

7x×2x=3584

14x²=3584

x²=3584/14=256

x=√256=16

length=7x=7×16=102 (m or c.m) , breadth=2x=2×16=32 (m or c.m)

Perimeter of rectangular field=2(l+b)

=2×(102+32)=2×134=268 (m or c.m)
