Question

a rectangle has the same area as that of a square. The length and the breadth of the rectangle are 20 cm and 5 cm respectively. calculate the area of the rectangle. find the area of the square .hence find its side. calculate the perimeter of rectangle and square​

Answer 1

Step-by-step explanation:

length=20cm

breadth=5cm

area=Length×breadth

=(20×5)cm

=100cm

Answer 2

Answer:

Area of rectangle is =l*b

Area of rectangle =20*5=100cm^2

therefore area of square is =100cm^2

area of square = Side *side

so 10*10= 100

so the side of square is 10 CM.

perimeter of rectangle =2(l+b)

= 2(20+5)

= 50 cm

perimeter of square is = 4*side

= 4*10=40cm
