Question

if a rectangle has a breadth of 8 m and has a perimeter of 36 m, then what is the length?​

Answer 1

Answer:

Length is equals to 10 m

Step-by-step explanation:

Perimeter of a rectangle = 2×(length+breadth)    - eq.1

It is given that breadth = 8 m and perimeter = 36 m

Putting the values in eq.1

36 = 2×(length+8)

36/2 = length+8

18 = length+8

18-8 = length

∴ length = 10 m

Answer 2

Answer:

Length= 10m

Step-by-step explanation: Here Formula of perimeter of rectangle

P = 2 ( l + b )

Given P = 36 , b = 8 fill the values

36 = 2 ( l + 8 )

36 = 2l + 16

36 - 16 = 2l

20 =  2l

20 = l

2

l = 10m
