5. The length of a rectangular hall is 4 meters less than 3 times the
breadth of the hall. What is the length, if the breadth is 'b' meters?
6. The side of a regular hexagon is denoted by 'R'. Express the
Perimeter of the hexagon using 'k'.

Step-by-step explanation:

5. Breadth of hall=b m

so: length of hall is 3 times the breath

so equation is 3b-4

6.

All sides of a regular hexagon=R

We know that all hexagon sides are equal

Therefore, AB=BC=CD=DE=EF=A F= the length (l)

5) length = (3 × b) - 4 = 3b - 4 metres

6) the sides are denoted as R

We know that, all the sides of a regular hexagon are equal.

Therefore the perimeter of the hexagon denoted as k

k = R + R + R + R + R + R

k = 6R

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
