Question

in the figure find the area of the parallelogram​

Answer 1

Answer:

Area of a parallelogram is breadth multiply by height

h=13,b=20

20×13=260

Answer 2

Answer:

Area of Parallelogram = 240 cm2

Step-by-step explanation:

To get the area of whole parallelogram, let's divide it in three parts, A, B and C

Cleary, A and C are Right Triangles with identical areas. While B is a Rectangle.

Hence, Area of Parallelogram = Area of A + Area of B + Area of C.

Length of perpendicular is unknown, we can apply Pythagoras theorem to get it,

$l = \sqrt{ {13 }^{2} - {5}^{2} } = 12$

Area of Triangles A and C is given by,

$a = \frac{1}{2} \times base \times height$

Hence, Area of A = Area of C = 1/2•(12x5)

=30 cm2

Area of Rectangle B is given by,

$a = length \times breadth$

Hence, Area of B = 15 x 12

= 180 cm2

Therefore, Area of Parallelogram = 30 + 30 + 180 =240cm2
