Question

lenth=6hm ,breadth=8 dam find perimeter and area​

Answer 1

The perimeter of rectangle = 136 dam and

The area of rectangle = 480 $dam^{2}$

Step-by-step explanation:

Given,

The length of rectangle(l) = 6 hm  and

The breadth of rectangle(b) = 8 dam

To find, the perimeter and area of rectangle = ?

∵ 1 hectometre( hm) = 10 decametre (dam)

∴ The length of rectangle(l) = 6 × 10 dam = 60 dam

We know that,

The perimeter of rectangle = 2(l + b)

= 2(60+ 8) dam

=  2(68) dam

= 136 dam

Also,

The area of rectangle = l × b

= 60 × 8 = 480 $dam^{2}$

Hence, the perimeter of rectangle = 136 dam and

the area of rectangle = 480 $dam^{2}$.
