Question

Find the perimeter of a rectangle whose area is 1380cm and its breadth is 23cm

Answer 1

Answer:

166 cm

Step-by-step explanation:

area = length ×breadth

1380=X×23

X=1380÷23

X=60=length

perimeter = 2(l+b)

              =2(60+23)

               =2(83)

               =166cm

Answer 2

Answer:

Perimeter is 166 cm

Step-by-step explanation:

Area = 1380 cm²

Breadth = 23 cm

Area = l * b

=> 1380 = l * 23

=> l = 1380 / 23

=> l = 60

Perimeter of rectangle = 2 (l + b)

=> P = 2 (60 + 23)

=> P = 2 * 83

=> P = 166 cm

Perimeter is 166 cm
