Answer:
Step-by-step explanation:
Surface area is the total surface. So first, find each surface...two triangles, same size and three rectangles, same size.
So you will have to add each....triangle+triangle+rectangle+rectangle+rectangle.
Area of a triangle = 1/2(b)(h) with b=base and h=height
Plug in knowns 1/2(15)(13)=A
Multiply 15X13=195 Then divide by 2. 195/2=97.5
The area of each triangle is 97.5 yd.
Area of a rectangle = (L)(W) with L=Length and W=Width
Plug in knowns (15)(24)=A Now, multiply
15X24=360
The area of each rectangle is 360 yd.
We need to add two triangles for front and back. and three rectangls.
97.5+97.5+360+360+360=1275
Surface area is 1,275 yd.
Ok well apparently you can't just put the answer and it has to be written out so its 15.75 divided by 1.75
In conclusion, it's 9.
Answer:
15×8 120
Step-by-step explanation:
times 15 with 8
-5/2 is equivalent to -2.5, and if you multiply 2.5 by 2 you get 5, and you have to have the negative, so add that to the 5 and you get -5. Hope this helps!
