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.
