Answer 1

Answer:

Neeta should buy 72 m of ribbon.

Answer 2

Answer:

Given:-

Neeta wants to frame a picture of length 2.5m and breadth 180cm

To find:-

The total length of the ribbon that Neeta should buy

Solution:-

As the rectangle will have length and breadth

So we need to calculate the perimeter of the ribbon

So picture is in rectangle size and ribbon is also in that size

Measures of pictures dimensions

Length =2.5m

Breadth=180cm

First we need to convert length measure to cm as remaining breadth's measure are in cm

To calculate the perimeter of rectangle it's dimensions should be like measures

By converting we get,

1m=100cm

2.5m=2.5×100cm

=250cm

As we know,

Perimeter of rectangle=2(length+breadth)

on substituting values we get,

=2(250cm+180cm)

=2(430cm)

=860cm

Therefore Neeta should buy 860cm length of ribbon

Additional information:-

$\huge\mathfrak\pink{More \: formula \: of \: perimeters}$

Perimeter of triangle=Sum of all sides

Perimeter of square=4×Side

Perimeter of rectangle=2(length+breadth)

Perimeter of circle =2πr

Perimeter of semicircle=

$\frac{2\pi \: r}{2} + d$

$or \: \pi \: r + d$

r=radius

d=diameter
