Sam created a porch that was part wooden and part concrete, as shown in the figure below.Note: Figure not drawn to scale

If a = 18 ft, b = 24 ft, and c = 30 ft, what is the total area of the porch? Assume that the wooden part is a right triangle and the concrete part is a square.
A.
186 ft2
B.
102 ft2
C.
1,260 ft2
D.
1,116 ft2

Answers

Answer 1

Answer: ok
totl area=trianglearea+squarearea

traignelarea=1/2(base)(height)

squarearea=side^2

we see
a=18
b=24
c=30

c=side of the square
a=base
b=height

so
trianglearea=1/2ab=1/2*18*24=216

squaerarea=side^2=c^2=30^2=900

add
216+900=1116

answer is D, 1116 ft^2

Answer:

h(2)= -17

Step-by-step explanation:

Answer:

h(x) = 31

Step-by-step explanation:

When it says find h (2), you will have to replace x with 2

h(x) = 3x^2 -5

h(x) = 3(2)^2 -5

h(x) = 6^2 - 5

h(x) = 36 - 5

h(x) = 31
