The area of a rectangle is 259 cm2 and its lenght is 18.5 cm find

crimeas [40]

The breadth of rectangle is 14 cm

The perimeter of rectangle is 65 cm

Solution:

Given that,

Area of rectangle = 259 square centimeter

Length of rectangle = 18.5 cm

The area of rectangle is given by formula:

$Area\ of\ rectangle = length \times breadth$

<h3>Find the breadth:</h3>

Substitute the given values in above formula:

$259 = 18.5 \times breadth\\\\breadth = \frac{259}{18.5}\\\\breadth = 14$

Thus breadth is 14 cm

<h3>Find the perimeter:</h3>

The perimeter of rectangle is given by formula:

$Perimeter = 2(length + breadth)$

Substitute the given values in above formula:

$perimeter = 2(18.5+14)\\\\perimeter = 2(32.5)\\\\perimeter = 65$

Thus perimeter of rectangle is 65 cm

The vertices of a polygon are P(0,4), Q(5,4), R(5,−3) and S(0,−3). What is

andrezito [222]

Answer:

Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

$a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} } = \sqrt{25} =5$

The distance of QR

$b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} } = \sqrt{49} =7$

The distance of RS

$c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} } = \sqrt{25} =5$

The distance of PS

$d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} } = \sqrt{49} =7$

Step(ii):-

Perimeter of the polygon

= sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

Final answer:-

Perimeter of the polygon p = 24

A temperature of –25°c is equivalent to: a. 248 k. b. 25 k. c. –25 k. d. 298 k.

SpyIntel [72]

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15;

So, T(K) = -25 + 273.15;

T(K) = 248.15;

The correct answer is a.
