Question

A square of side 40cm and a rectangular field with length of 60cm respectively have the

same perimeter. Find the breadth of the rectangle also find Which field has a larger area?​

Answer 1

Answer:

breadt of the rectangle is b=20

Step-by-step explanation:

according to question

perimeter of square =perimeter of rectangle

4s=2(l+b)

4×40=2(60+b)

by solving

80=60+b

b=80-60

b=20

Answer 2

Answer:

here,

perimeter of square=perimeter of rectangle

so ,

4.(side)= 2(l+b)

4.40 = 2(60+b)

160/2=60+b

80= 60+b

80-60=b

b=20

now,

area of rectangle=l.b

=60*20

=1200cm²

area of square=( side)²

= (40)²

= 1600

hence, square has large area
