Answer 1

QUESTION➡

The area of rectangle is 500 square cm and one of its side is 20 cm. Find the perimeter of the rectangle ?

SOLUTION➡

Let the length be x cm

Area of rectangle = 500 cm^2

Breadth = 20 cm

_______________________________

Area of rectangle = Length × Breadth

500= x × 20

=> x = 25 cm

_____________________________

Perimeter of rectangle = 2(l+b)

= 2(25+20)

= 2× 45

= 90 cm

_____________________________

Therefore,

Perimeter of the rectangle is 90 cm

Answer 2

Answer:  Perimeter of rectangle  is 90 cm.

Step-by-step explanation:

Let  the one side be breadth(b)=20cm.

Area of rectangle=length(l)* breadth(b)

500 =l*20                         [we put  20 in place of breadth]

l=500/20

length (l)=25cm

Perimeter of rectangle=2(length+breadth)

                                      =2(25+20)cm

                                     =2*45 cm

                                     =90cm
