Answer:
divide 40 by 8cm. it's pretty self explanatory
Step-by-step explanation:
[tex]40cm \div 8cm[/tex]
divided 8 on both sides.
divide 40 from 8 and you're left with 5 cm. the length is 5.
Answer:
length = 12 cm
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2b ( l is the length and b the breadth )
let x be the length , then
2x + 2(8) = 40
2x + 16 = 40 ( subtract 16 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
That is the length is 12 cm
