Question

find the perimeter of a table top measuring 2 m 15 cm by 1 m 65 cm

Answer 1

❤$\mathfrak{\huge{Hola!!}}$❤

Perimeter of a rectangular table top = 2 ( l + b )

Given:
l = 2m 15 cm
=》 2.15 m

b = 1m 65 cm
=》 1.65 m

Put the values in the formula:

Perimeter = 2 ( 2.15 + 1.65 )

=》 2 ( 3.8 )

=》 7.6 m

Answer 2

$\underline{\underline{\Huge\mathfrak{Solution ;}}}$

Given that ;-
• Length = 2 m 15 cm
• Breadth = 1 m 65 cm

Find the Perimeter ;-

First of all , changing all the values in a mixed measurement ;-
• 2 m 15 cm = 2.15 m
• 1 m 65 cm = 1.65 m

Now ,
We know that ;
• Perimeter = 2 ( Lenght + Breadth )

So ,
$= > 2(2.15 + 1.65) \:$
$= > 2 \times 3.8 = 7.6 \:$

Hence ,
The Perimeter = 7.6 m^2
