Question

A square has a side 60 cm . A rectangle with the same perimeter has a side 70 cm. Compare their perimeters and areas

Answer 1

Answer:

Their perimeters are given equal .

Step-by-step explanation:

4a =2(L+B)    equation-1

Area

a*a= L*B  

60*60=70*50                { Value of B can be find out using equation-1 }

3600=3500

area of square is greater than rectangle by 100 cm square.

Answer 2

Perimeter of square is equal to the perimeter of rectangle

Area of square is more than Area of rectangle

Step-by-step explanation:

Side of square = 60 cm

Perimeter of square = $4 \times Side = 4 \times 60 = 240 cm$

Area of square =$Side^2 = 60^2 = 3600 cm^2$

A rectangle with the same perimeter has a side 70 cm.

Perimeter of rectangle = 2(l+b)=2(70+b)=240

70+b=120

b=120-70

b = 50 cm

Area of rectangle = lb =$70 \times 50= 3500 cm^2$

Perimeter of square is equal to the perimeter of rectangle

Area of square is more than Area of rectangle
