Question

the length and breadth of a rectangle are 13/2m and 12/5m respectively. find the area and perimeter of the rectangle ​

Answer 1

Answer:

Length = 13/2 m

Breadth = 12/5 m

Perimeter = 2 (l+b) = 2 (13/2 + 12/5) = 2 (89/10) m = 89/5 m or 17.8 m

Area = l×b = 13/2 × 12/5 = 78/5 m²

Answer 2

Answer:

Area of that rectangle is 15.6 cm²

Perimeter of that rectangle is 17.8 cm.

Step-by-step explanation:

The length of rectangle is 13/2 cm

It's breadth is 12/5 cm.

We know that perimeter of a rectangle is 2 x ( length + breadth)

Therefore perimeter of given rectangle is, 2 x (13/2 + 12/5)

2 x( 65+24/10)     ( since LCM of 2 and 5 is 10)

= 2 x (89/10)

= 89/5

= 17.8 cm.

We know than area of a Rectangle is (length x breadth)

Therefore area of given rectangle is,

13/2 x 12/5

=156/10

=15.6 cm²
