<em><u>2</u></em><em><u>1</u></em><em><u>y</u></em><em><u>d</u></em><em><u>^</u></em><em><u>2</u></em>
Step-by-step explanation:
join the centre to all the vertex,
since this figure is of regular pentagon, it's will form 5 equal triangle of equal area!
now area of one such triangle is
1/2 ×base ×height
=1/2 ×3.5x2.4 (yd^2)
=4.2 yd^2
now the pentagon is sum of 5 such equal triangle,so it's are will be
5×4.2 (yd^2)
=21 yd^2
