Question

Perimeter of a rectangle is 13cm. if its width is 11/4
cm
, find its length.​

Answer 1

Answer:

the formula for perimeter is 2(l+b).

therefore 2(l+11/4)=13

l+11/4=13/2

l=13/2-11/4

l=3.75

Answer 2

GiVeN :-

Perimeter = 13cm

Width/Breadth = 11/4cm

To FiNd :-

Length of the rectangle = ?

FoRmUlA uSeD :-

Perimeter of rectangle = 2(length+breadth)

SoLuTiOn :-

Perimeter = 13cm

Width/Breadth = 11/4cm

According to Question ,

$\rm \rightarrow Perimeter = 2(l+b)$

$\rm \rightarrow 13 = 2(l + \frac{11}{4} )$

$\rm \rightarrow 13 = 2l + \frac{22}{4}$

$\rm \rightarrow 13 - \frac{22}{4} = 2l$

$\rm \rightarrow \frac{52 - 22}{4} = 2l$

$\rm \rightarrow \frac{30}{4} = 2l$

$\rm \rightarrow l = \frac{30}{4 \times 2}$

$\rm \rightarrow l = \frac{ \cancel{30}}{ \cancel{8}}$

$\boxed{ \rm{ \therefore length = \frac{15}{4} }}$
