Question

length
$40 \times \frac23$
breadth
$19 \times \frac12$
find its perimeter
​

Answer 1

Answer:

= 217/3 unit

Step-by-step explanation:

Length = 40 x 2/3 = 80/3

breadth = 19 x 1/2 = 19/2

Area of perimeter = 2(length + breath)

= 2(80/3 x 19/2)

= LCM is 6

= 2({80*2}/{3*2} + {19*3}/{2*3})

= 2(160/6 + 57/6)

= 2(217/6)

= 2 * 217/6

= 217/3 unit
