Answer:

84cm^2

Step-by-step explanation:

The pyramid's SA is the square at the bottom plus the triangles on the side.

The square is 6x6=36.

Per triangle, it's BxH/2. B=6. H=4. Therefore, per triangle has a SA of 12 cm^2.

There are 4 triangles. 48 cm^2 in total for the triangles

36cm^2+48cm^2=84cm^2

Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Step-by-step explanation:

we know that

The isosceles trapezoid has :

Two parallel sides not equal in length called its bases (KL and NM)

Two non-parallel sides equal in length (LM and NK)

$NK=\sqrt{5}\ units$

The perimeter is equal to

$P=KL+LM+NM+NK$

substitute the values

$P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}$

$P=(3\sqrt{2}+2\sqrt{5})\ units$

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
