Find the areas of the following geometric figure. find the area of a trapezoid whose parallel sides measure 8.5 m and 4.5 m and whose altitude is 6.5 m to the nearest tenth area =

42.25 m^2

Step-by-step explanation:

The area of a trapezoid = (h/2)(a + b) where h = altitude, and a and b are the 2 parallel sides.

So the area of this one = (6.5 / 2) ( 8.5 + 4.5)

=  42.25 m^2

What the guy above said except 42.3. Not sure why so many users seem to think the nearest tenths means the nearest hundredth.

answer:      

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
