Question

In a parallelogram base=31.5cm

height=18cm find area

Answer 1

area of triangle

The area of triangle = 1/2 bh

in this parallelogram their are 2 triangles

so its area = 2 × 1/2 (bh ) = bh

b = 13.5cm and h = 18 cm ;  ( 31.5 - 18 = 13.5 )

area = 13.5 × 18

= 243cm^2

area of square

area of square = side × side

= 18 × 18

= 324 cm^2

area of oarallelogram = area of 2 triangle + area of 1 square

    243 + 324

   = 567 cm^2

Answer 2

The Area of a parallelogram is "567 cm²".

Step-by-step explanation:

$The \ given \ values \ are:\\\\The \ base \ of \ a \ parallelogram,b=31.5 \ cm\\The \ height,h=18 \ cm\\The \ Area ,A=?\\\\As \ we \ know,\\\\The \ Area \ of \ a \ parallelogram,\\A=base\times height\\\\On \ putting \ the \ values \ in \ the \ above \ formula,we \ get\\\\A=31.5\times 18\\\\A=567 \ cm^2$
