Question

Breadth of a rectangle is 27 cm less than its length.If the perimeter is 3m 6cm then

Answer 1

Answer:

Length of the rectangle = 90 cm

Breadth of the rectangle = 63 cm

Step-by-step explanation:

Formula used:

Perimeter of rectangle =2[Length+Breadth] units

Let $l\:and\:b$ be the length and breadth of the rectangle respectively.

Given:

$b=l-27$.....................(1)

Perimeter = 3m 6 cm

Perimeter = 306 cm

$2(l+b)=306$

$l+b=153$

$l+(l-27)=153$ (using (1))

$2l-27=153$

$2l=153+27$

$2l=180$

$l=90\:cm$

put l=90 in (1)

$b=90-27$

$b=63\:cm$

Length of the rectangle = 90 cm

Breadth of the rectangle = 63 cm
