Question

if the perimeter of a trapezium is 90 cm it's non parallel sides are equal to 16 cm each and its height is 9 cm, find the area of trapezium​

Answer 1

Answer:

261 cm^2

Step-by-step explanation:

perimeter =a+b+c+d

90=a+b+16+16

90=a+b+32

90-32=a+b

a+b=58 cm

area = 1/2(a+b)×h

= 1/2×58×9

= 29×9

=261 cm^2
