Uh, so yeah I need help with this problem? Anyone?

48.25 mm^2

Step-by-step explanation:

Well you really need to find 4 sides.

There are 2 different sides, one is the bottom and the rest are the sides.

All sides are the same except for the bottom.

The bottom has the two measures of base and height, base being 5 and height being 4.3

Following the formula of an area for a triangle a=bh/2, you’d hey 10.75.

Now for the rest you have a base of 5 and a height of 5, same process, different numbers. You’d get 12.5. Since there are only 3 faces remaining and all of them are the same we can triple 12.5 to 37.5 (by multiply by 3) and then add up the two numbers.

37.5+10.75= 48.25mm

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
