Question

the area of square field is5184m square a rectangular field whose length is twice its breadth has its perimeter equal to the perimeter of the square field find the area of the rectanggular field

Answer 1

answer is:

side of square field=√5184m^

=72m

perimeter=72m×4=288m

perimeter of square field=perimeter of rectangular field=288m

now,

let the breadth of rectangular field be x

then,length=2x

according to the question,

perimeter of rectangle=2(l+b)

=288m=2(x+2x)

=288m=2×3x

=288m/6=x

=48m=x

thus,

breadth=48m

length=48m×2=96m

area of rectangular field=l×b

=48m×96m

=4608m^.

mark as brainliest.

Answer 2

side of the square is 72

perimeter of square is 288

length of the rectangle is 96

breadth of the rectangle is 48

area of rectangle is 4608

thank you for this sum it helped me revise for my maths exam
