Question

the perimeter of a rectangle is 160 cm if the breadth of the rectangle is 30 cm find its length also find the area of rectangle
​

Answer 1

Step-by-step explanation:

Perimeter of the rectangle = 160cm

Breadth = 30cm

Length = ??

We know that,

Perimeter of a rectangle = 2(l + b)

=> 160 = 2(l + 30)

=> 160/2 = l + 30

=> 80 = l + 30

=> l = 80-30

=> l = 50cm.

Answer 2

Answer:

50 cm

1500 cm

Step-by-step explanation:

perimeter = 160cm

breadth = 30cm

let length = A

perimeter of rectangle = 2(l+b)

160cm. =. 2(A+ 30 cm)

160 cm/2 = A + 30 cm

80 cm. = A + 30 cm

80-- 30 cm. = A

50 cm. = A

Now , area of rectangle = l×b

= 30 cm× 50 cm

= 1500 cm square
