Answer:

Total students  = 1240

Step-by-step explanation:

Boys : girls = 11 : 9

Number of boys  = 11x

Number of girls  = 9x

11x - 9x = 124

       2x = 124

         x = 124/2

        x = 62

Number of boys  = 11x = 11 *62 = 682

Number of girls  = 9x   = 9*62    = 558

Total students  = 682 + 558 = 1240

AVprozaik [17]

Answer:

80 feet.

Step-by-step explanation:

Given:

The length of a rectangular garden is 10 yards and its width is 10 feet.

To find:

Perimeter of the garden in feet ?

Solution:

Length = 10 yards

1 yard = 3 feet

10 yards = 3 \times 10 = 30 feet

Breadth = 10 feet

Now, as we know:

Perimeter\ of\ rectangle=2(length+breadth)

                                       =2(30+10)\\ \\ =2(40)\\ \\ =80\ feet

Hence, the perimeter of the garden is 80 feet.
