Let a=18 cm, b=10 cm
Perimeter =42cm
{tex}\therefore a+b+c=42cm{/tex}
So, C=14 cm
{tex}\therefore \text{ S=}\frac{a+b+c}{2}\text{ =}\frac{18+10+14}{2}{/tex} = 21 cm
new area of triangles {tex}=\sqrt{21(21-18)\text{ (21}-\text{10) (21}-\text{14)}}\\ \text{= }\sqrt{21\times 3\times 11\times 7}{/tex}
{tex}\text{=21}\sqrt{11}\text{ }sq\text{ cm}{/tex}

In 20 dozen, there are 20 x 12 = 240 bananas for Rs 4 per piece
and 250 apples are for 4 Rs per piece.
Therefore, Apples are more costlier.

Let the triangle's of angle is x, y and z
we have to prove
x + y + z = 180 ..........(i)
we know that sum of two interior opposite angle is equal to exterior angle.
so, x + y = 180 - z ....... (ii)
By linear pair exterior angle is 180 - z when triangle's angle is z.
By (i) also we get
x + y = 180 - z ..........(iii)
Hence proved
(ii) and (iii) are the same, so we can say that the sum of the three angles triangle is 180o.
