For pieces of triangle,
a = 20 cm , b = 50 cm , c = 50 cm
.°. s = a + b + c / 2
= 20 + 50 + 50 / 2
= 120 / 2
= 60 cm
.°. a triangles area = √ s ( s - a ) ( s - b ) ( s - c )
= √ 60 ( 60 - 20 ) ( 60 - 50 ) ( 60 - 50 )
= √ 60 ( 40 ) ( 10 ) ( 10 )
= 200√6 cm²
.°. one colour of five triangles area ,
= 5 ( 200√6 ) cm²
= 1000√6 cm²
so, there are 1000√6 cm² cloth of each colour is required for the umbrella.

Here are the three numbers whose decimal expansion are non terminating and non recurring:-
1)√2 = 1.4142.........
2) √3 =1.73205......
3) √5 =2.236......
these values are non terminating and non recurring.
thus, we say them as irrational numbers.

{tex}let \: x = 0.12 \bar{5} \bar{4} \\ \\ or \: x = 0.12545454... \\ \\ 100x = 12.545454... \\ \\ 10000x = 1254.545454... \\ \\subtract : \\ 10000x - 100x = 1254.5454... - 12.5454... \\ \\ 9900x = 1242 \\ \\ x = \frac{9900}{1242} \\ \\ x = \frac{550}{69} \\ \\ thus \: \: \: 0.12 \bar{5} \bar{4} = \frac{550}{69} \:{/tex}

0.4x + 0.3y=1.7...(1)
0.7x - 0.2y= 0.8...(2)
multiplying eq 1 by 2 & eq 2 by 3, we get
0.8x + 0.6y = 3.4..(3)
2.1x - 0.6y = 2.4..(4) now adding eq 3&4
2.9x= 5.8
x=5.8/2.9
x=2
putting the value of x in eq (1)
0.4×2 + 0.3y=1.7
0.3y= 1.7-0.8
y=0.9/0.3
y=3
Answer x=2 y=3

The pointy where graph cut x-axis and y-axis are x-intercept and y-intercept.
The x-intercept is when y=0,
2x+3(0)=12
2x=12
{tex}x=\frac{12}{2}{/tex}
x=6
So, Graph cut x-axis at (6,0).
The y-intercept is when x=0,
2(0)+3y=12
3y=12
{tex}y=\frac{12}{3}{/tex}
y=4
So, Graph cut y-axis at (0,4).
Refer the attached figure for graph.

Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

i) p(x) = 5x - 4x² + 3
On putting x=0 ,
p(0) = 5(0) - 4(0)² + 3
= 0 - 0 +3=3
= 3
ii) (x) = 5x - 4x² + 3
On putting x= -1,
p(-1) = 5(-1) - 4(-1)²+ 3
= -5 - 4(1) + 3
= -5-4+3= -9+3= -6
= -6
iii) p(x) = 5x - 4x² + 3
On putting x=2
p(2) = 5(2) - 4(2)² + 3
= 10 – 16 + 3 = -6+3
= -3
