Calculate the perimeter and area for the parallelogram if a = 2.8 ,b = 16.5 and h = 11.5

Perimeter = 2(a+b)

= 2(2.8+16.5)

=2(19.3)

Perimeter = 38.6

Area=base x height

=2.8 x 11.5

=32.2

Given is a parallelogram

Perimeter = 2 ( sum of the length of non parallel sides )

= 2 ( 2.8 + 16.5 ) = 38.6

Area of parallelogram =

(1/2) ( sum of length of parallel sides )* corresponding perpendicular distance

( 1/2)( 2.8 + 2.8)( 11.5 ) = 32.2

Answer : perimeter = 38.6 unit .

Area = 32.2 square unit

what i would say the best answer is a. 40.5
