Answer:

340.8cm^2

Step-by-step explanation:

So surface area is basically the area of all the sides combined. And we know that the area of a triangle is 1/2bh, and for a rectangle it is LW. So there are three congruent rectangles, and one of those rectangle's area is 72 ( 6 x 12), so you can multiply that by 3 to find all three rectangles, which is 216. We also know that the two triangles are congruent. and the base is 12, and height is 10.4, so 12 x 10.4 is 124.8.

We take the total of the rectangles and the triangles to find the total surface area:

     216 + 124.8 = 340.8cm^2

The length of a rectangle is 9cm. more than half the width. Find the length if the perimeter is 60 cm.
I am Lyosha [343]

(60-18)/2=21 cm

21/2=10.5 - half of the width

9 is less than half of the width.

There are no reasonable solution for this task.
