Surface area of a rectangular pyramid = A + 1/2 p s
Where:
A = area of the base
p = perimeter of the base
s= salnt height = 5 in
A = Area of a rectangle = length x width = 8 x 4 = 32 in2
Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2
SA = 32 + 1/2 * 24 * 5 = 92 in2
Answer:
See explanation

Answer:
1,260 sq ft
Step-by-step explanation:
FORMULA TO FIND AREA OF A RECTANGLE: L*W, l=length, w=width
we can divide the figure into three other rectangles
rectangle one) length=20 width=10
so 20*10=200
rectangle 2) length=45, width=20
so 45*20=900
rectangle 3) length=20 width=8
so 20*8=160
now we add up the areas of the 3 rectangles to find the area of our figure
200+900+160=1,260 sq ft
hope this helps!
