To solve for the surface area of the pyramid, we make use
of the formula:
A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))
where,
l and w are the base of the pyramid = 100 mm
h is the height of the pyramid = 75 mm
Substituting the given values into the equation:
A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100
/ 2)^2 + 75^2))
A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)
A = 20,148.90 mm^2
Therefore the surface area of the pyramid is about 20,149
mm^2.

Answer:
7.1/10
8.1/5
9.1/5
Step-by-step explanation:
7.1/2*1/5
8.2/5*1/2
9.2/5*1/2
4/7 can be equivalent to 8/14 (Multiplied top and bottom of fraction by 2)
It can also be equivalent to 12/21. (Multiplied by 3)
16/28.
And so on.
It’s should be the second on so b and you should get it corrdct
