Question

) Perimeter of a rectangle is 20 m. Find its breadth when the length is 6 m.)

Answer 1

Step-by-step explanation:

Length = l = 25 m and Width = w = 15 m

∴ P = 2 ( l + w )

⇒ = 2 ( 25 + 15 )

⇒ = 2 x 40

⇒ = 80 m

Perimeter = 80 m

Answer 2

Answer:

width = 4m

length = 6m

perimeter = 20m

using the formula

P = 2 ( l + w )

solving for width

w = P – L = 20 – 6 = 4m

2 2

4m
