Question

if the three sides of an figure is 18m and the forth side is 16m and it's total are of the figuse is 303.514101feet..prove me how is it.​

Answer 1

Answer:

(24

21

−77)m

Step-by-step explanation:

Given radius of each sector=7m

Now area of sector with ∠C=

360

∠C

×πr

2

=

360

∠c

×π(7

2

)m

2

Area of the sector with ∠B=

360

∠B

×πr

2

=

360

∠B

×π(7

2

)m

2

And area of the sector with ∠H=

360

∠H

×πr

2

=

360

∠H

×π(7

2

)m

2

Therefore sum of the areas =

360

∠C+∠B+∠H

×π×49=77m

2

Semiperimeter=24 m

Therefore area of the triangular field =

s(s−a)(s−b)(s−c)

=24

21

m

2

So area which can not be grazed =(24

21

−77)m
