Answer:
360
Step-by-step explanation:
4(90)= 360
Answer:
3 and 1/2
Step-by-step explanation:
Well you already know your side lengths, so you use this formula S=1/2(A+B+C). For A put in one of your side lengths, for B put one of your side lengths, and for C put one of your side lengths. After you do that solve. But your not done. Once you find out what S equals by doing the formula I just showed you, you have to do another formula which is A= S(S-A)(S-B)(S-C). Once again plug in your side lengths for A,B, and C but then plug in your S value. (Remember you already found your S value by doing the first formula I showed you). Then do the math and then you will find your answer.
Answer:
1232 m^2.
Step-by-step explanation:
The net consists of 2 triangles and 3 rectangles.
Area of each triangle = 1/2 * 24*7 .
Area of 1 rectangle = 25 * 19.
The other 2 have areas 24*19 and 7 * 19.
Therefore the surface area of the prism
= 2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19
= 1232 m^2.
