Question

12. The perimeter of a trapezium is 104 m, its non-parallel sides are 18 m and 22 m,
and its altitude is 16 m. Find the area of trapezium.​

Answer 1

Answer:

a and b are parallel side

Step-by-step explanation:

a+b+18+22=104

a+b =104-40

a+b= 64m

area = (a+b/2) × h

= (64/2)16

=32× 16

=512m^2

Answer 2

Answer:

$512m {}^{2}$

Step-by-step explanation:

Using the formulas

A=hm

P=2m+c+d

Solving for A

$a = h \frac{p - c - d}{2}$

$= 16 \frac{104 - 18 - 22}{2}$

$= 512m {}^{2}$
