Radha made a picture of an aeroplane with coloured papers as shown in the given figure. Find the total area of the paper used.

**For triangle I**

This triangle is an isosceles triangle.

Perimeter = 2*s* =
(5 + 5 + 1) cm = 11cm

Area of the triangle

**For quadrilateral II**

This quadrilateral is a rectangle.

Area = *l × b*
= (6.5 × 1) cm^{2 }= 6.5 cm^{2}

**For quadrilateral
III**

This quadrilateral is a trapezium.

Perpendicular height of parallelogram

Area = Area of parallelogram + Area of equilateral triangle

=
0.866 + 0.433 = 1.299 cm^{2}

Area of triangle (IV) = Area of triangle in (V)

Total area of the paper used = 2.488 + 6.5 + 1.299 + 4.5 × 2

=
19.287 cm^{2}
