Question

the length of a rectangular board is 6m and the perimeter is 20m. Find the width of the board?​

Answer 1

Answer:

width=4

Step-by-step explanation:

formula=2 x(l+b)

length=6

perimeter=20

breadth=4

perimeter=2 x(6+4)=20

Answer 2

Answer:

4m

Step-by-step explanation:

Length (l) of the rectangular board: 6m

Perimeter (P) of the rectangular board: 20m

Width of the board: w

We know that P=2(l+w)

                       w = (P/2) - l

Solving for w

= (20/2) - 6

= 4
