26 × (–48) + (–48) × (–36)
= [– (26 × 48)]+ (48 × 36) . . . . [a × (–b) = – (a × b)
= (–1248) + 1728 (–a) × (–b) = a × b
= 480

The Area of a triangle is calculated by
{tex}\frac{1}{2} \times base + hight{/tex}
Given :-
{tex}base = \frac{43}{4} cm \\ and \\ hight = \frac{63}{4} cm{/tex}
Putting the values in the formula we get
{tex}Area \: of \: the \: triangle \: \\ = (\frac{1}{2} \times \frac{43}{4} \times \frac{63}{4 })cm {}^{2} \\ \\ = ( \frac{2709}{32})cm {}^{2} \\ \\ = 84.65625 cm ^{2} \\{/tex}

Let the interior angle of the regular polygon be x.
Therefore, the exterior angle is x/4.
Exterior angle + adjacent interior angle = 180°
x/4 + x. = 180°
5x /4. = 180°
x. = 180° * 4/5
= 144°
The interior angle is 144°.
The exterior angle is 36°.
Let n be the number of sides.
n = 360°/ exterior angle
= 360° / 36°
= 10
The number of sides of a regular polygon is 10.

In ∆ABC, AB = 15 cm , BC = 13 cm and AC = 14 cm.
By Heron's formula ,
S = ( A + B + C ) / 2
S = ( 15 + 13 + 14 ) / 2
S = 42 / 2
S = 21
Now, area of triangle
= √S (S–A) (S–B) (S–C)
= √21 (21–15) (21–13) (21–14)
= √21 (6) (8) (7)
= √7056
= 84 cm2
Again,area of triangle = 1/2×base×altitude=84 cm2
1/2×14×altitude = 84
7 × altitude=84
altitude = 84/7
Altitude = 12cm
Therefore, the area of ∆ABC is 84cm² and its altitude on AC is 12 cm.

Distance =350
time =7/2
speed =distance ÷time
=350×2/7
=100 km/hr
speed =100 km/hr
time = 5hours
distance = 100 × 5
= 500 km

So 1 labourer will take (15{tex}\times{/tex}22) = 330 days.
Now, 33 labourers will take 330/33 = 10 days.
