The perimeter of floor is 56mThe length of non parallel sides is 12mSo the sum of lengths of parallel sides is -a-b-56-x2212-12-x2212-12-32mThe height of trapezium-10mThe area of floor -12-a-b-xD7-h-12-32-xD7-10-160m2

If the perimeter of a trapezium-shaped floor is $56$ m, its non-parallel sides are $12$ m each and the altitude is $10$ m, find the area that the floor covers.

The perimeter of floor is $56 m$

The length of non parallel sides is $12 m$

So the sum of lengths of parallel sides is $(a + b) 56 - 12 - 12 = 32 m$

The height of trapezium= $10 m$

The area of floor = $\frac{1}{2} (a + b) \times h$

= $\frac{1}{2} (32) \times 10$

$= 160 m^{2}$

The perimeter of floor is 56mThe length of non parallel sides is 12mSo the sum of lengths of parallel sides is (a+b)56−12−12=32mThe height of trapezium=10mThe area of floor =12(a+b)×h=12(32)×10=160m2
