Question

The perimeter of rectangle is 8 metre and length 80 cm find in its breadth and area

Answer 1

Answer:

perimeter of rectangle=2(l+b)

8m = 2×(80+b)

8m = 160b

b= 160/8

b= 20

area of rectangle= l× b

= 80×20

= 1600

Answer 2

Answer:

Perimeter of rectangle = 2(l +b)

8m = 2(80 + b)

8m = 160 + b

b = 160/8

b = 20 m

Area of rectangle = l × b

= 80 ×20

= 1600 m
