$4$ m is:

0%
$16$ m
0%
$16$ cm
0%
$4$ m
0%
$12$ m

Explanation

Perimeter of a square =

$4 \times side$

$4 \times 4 = 16 m$

Perimeter of square of sides is

0%
$4*side$
0%
$\displaystyle side^{4}$
0%
$4 + side$
0%
$\displaystyle side\times side$

If the length and breadth of a rectangle are doubled then its perimeter is

0%
tripled
0%
doubled
0%
made half
0%
none of these

Explanation

Perimeter of rectangle

$= 2(l+b)$

Here length

$= l$ and breadth

$= b$
If the length and breadth of a rectangle are doubled.
then length

$= 2l$ and breadth

$= 2b$

$\therefore$ perimeter of new rectangle would be

$2(2l+2b) = 4(l+b) = 2.2(l+b)$

$\therefore$ if the length and breadth of a rectangle are doubled then its perimeter is also doubled.
Option B is correct.

$4\ m$ is

0%
$16\ m$
0%
$16\ cm$
0%
$4\ m$
0%

$20\ mm$ in length. Find the area of stamp in

$cm^{2}$

0%
$0.24$
0%
$240$
0%
$24$
0%
$2.4$

Explanation

As we know that,

$1\ cm=10\ mm$

So,

$1\ mm=0.1\ cm$

Given:-

Length

$= 20\ mm$

$=20\times 0.1\ cm$

$=2\ cm$

Breadth

$= 12\ mm$

$=12\times 0.1\ cm$

$=1.2\ cm$

Area of stamp

$=$ Length

$\times$ Breadth

$=2\times 1.2$

$=2.4\ cm^2$

Hence, option

$D$ is correct.

Fill in the blanks:
Perimeter of the square of side

$4$ cm = _____ cm

0%
$16$
0%
$12$
0%
$18$
0%
$8$

Explanation

Given, Side of a square =

$4$ cm

Perimeter of a square

$= 4 \times side$

So, perimeter of the square

$= 4 \times 4 \ cm= 16 cm$

Hence, the perimeter of the square is

$16\ cm$

An athelete takes

$50$ m long and

$250$ m wide. Then the total distance covered by him is ______ .

0%
$150$ m
0%
$75$ m
0%
$1000$ m
0%
$3000$ m

Explanation

Given, Breadth of the rectangular park

$b=250$ m

and Length

$l=50$ m

Perimeter of the park

$=2(b+l)$

$=2\times (250+50)$

$=2\times 300$

$=600$ m

Given: Athlete take

$5$ rounds around the rectangular park

So, the total distance covered by the athlete

$=$

$5\times 600$ m

$=3000$ m

How many paving stones each measuring

$2.5\text{ m}$

$\times 2\text{ m}$ are required to pave a rectangular courtyard

$30\text{ m}$ long and

$16.5\text{ m}$ wide?

0%
$105$
0%
$89$
0%
$99$
0%
$84$

Explanation

Area of paving stones

$=2.5 \times 2=5 \text{ m}^2$

Area of courtyard

$=30 \times 16.5=495 \text{ m}^2$

Now,

Number of paving stones required

$=$ area of courtyard

$÷$ area of paving stone

$= 495 ÷ 5$

$= 99$ paving stones

So option C is the correct answer.

$2$ rectangles

What is the perimeter of the big rectangle?

0%
$11r+12$
0%
$22r+24$
0%
$11r$
0%
$11r+6$

Explanation

$\Rightarrow$ Length of a big rectangle

$(l)=(7r+3+3)cm=(7r+6)cm$

$\Rightarrow$ Breadth of a big rectangle

$(b)=(4r+3+3)cm=(4r+6)cm$

$\Rightarrow$ Perimeter of big rectangle

$=2(l+b)cm$

$=2[(7r+6)+(4r+6)]cm$

$=2[11r+12]cm$

$=22r+24\,cm$
