Answer 2

Answer:

20.475 cm²

Step-by-step explanation:

Area of a rhombus = pq/2 cm²

= 8.4 x 6.5 /2 cm²

=54.6/2 cm²

= 27.3 cm²

area of the shaded portion= area of rhombus - area of triangle

= 27.3 cm² - area of the triangle

one side of the triangle= 8.4/2 = 4.2

other side of the triangle = 6.5/2

in a rhombus, diagonals intersect at right angle. therefore, it is a right angle triangle.

area of right angled triangle= 1/2 x bh

= 1/2 x 4.2 x 6.5 /2

= 4.2 ×6.5/4

= 27.3/4 cm²

area of shaded portion =27.3 cm² - 6.825 cm²

= 20.475 cm²
