Thread border around a table - Rectangle - Mensuration problem solver

James need to wrap a rectangular table by a thread. The length of the table is 3m and the width is 2m. Find the length of the thread required. (hint : perimeter is the length of the thread).

thread border around a table

length = 3
width = 2
p = 2 * ( l + w )
perimeter = 2 * ( 3 + 2 )
perimeter = 10
So the perimeter is 10

Rectangle :

A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

Rectangle Formulas :

A =  l * w

p = 2 * ( l + w )

l =  A / w

w =  A / l

d = sqrt( l ^ 2 + w ^ 2)


where,

l = length
w = width
d = diagonal
p = perimeter
A = area
