Question

A square a rectangle have a same perimeter if the side of a square is 60cm and the length of the rectangle is 80 metre then whose area is more than how much

Answer 1

Answer:

Area of rectangle is more by 1200 m

Step-by-step explanation:

P of square=P of rectangle

P of square = 4s

s = 60 cm

P = 60×4

  = 240 cm

Length of rectangle= 80 cm

Breadth = b

Perimeter= 240 cm

2(80+b)=240

160+b=240

b= 240-160

 = 40 cm

Breadth = 40 cm

Area of square = s×s

                         = 60×60

                         = 3600 cm²

Area of rectangle = l×b

                              = 80×60

                              = 4800 cm²

4800>3600

∴ Area of rectangle is more by 1200cm
