Question

find the area of the following quadrilaterals

Answer 1

Hi friend
---------------
Your answer
---------------------

(a) Area of the quadrilateral = area of ∆ABC + area of ∆ADC

=> [(1/2 × 3 × 6) + (1/2 × 5 × 6)] cm²

=> [9 + 15] cm²

=> 24 cm²

(b) Area of the rhombus

=> [1/2 × 6 × 7] cm²

=> 21 cm²

(c) Area of the parallelogram = area of the two triangles

Area of two triangles in a parallelogram formed by a diagonal are equal.

So,
-----

Area = [2 × (1/2 × 2 × 8) ] cm²

=> [2 × 8] cm²

=> 16 cm²
