Question -
Answer -
For triangle I
This triangle is an isosceles triangle.
Perimeter = 2s =(5 + 5 + 1) cm = 11cm
Area of the triangle
For quadrilateralII
This quadrilateral is a rectangle.
Area = l× b = (6.5 × 1) cm2 = 6.5 cm2
For quadrilateral III
This quadrilateral is a trapezium.
Perpendicular height of parallelogram 
Area = Areaof parallelogram + Area of equilateral triangle
= 0.866 + 0.433 = 1.299 cm2
Area oftriangle (IV) = Area of triangle in (V)
Total areaof the paper used = 2.488 + 6.5 + 1.299 + 4.5 × 2
= 19.287 cm2
