Fill in the blanks.
(i) Area of triangle
(ii) Area of a ||gm = (............)× (.............)
(iii) Area of a trapezium
(iv) The parallel sides of a trapezium are 14 cm and 18 cm and the distance between them is 8 cm. The area of the trapezium is ...... cm2.
(i) Area of triangle = × (base) × (height).
(ii) Area of || gm = (base) × (height).
(iii) Area of trapezium is × (sum of parallel sides) × (height)
(iv) Given
Length of parallel sides is 14cm and 18 cm
Height (h) = 8 cm
We know that area of trapezium is × (sum of parallel sides) × height
Therefore Area of trapezium = × (14 +18) × 8 = 128 cm2.
