Find the area of the triangle that has a base of 5 in. and a height of 3 and 3/4 in.
2 answers:
The formula for area of a triangle given its base and its height is A = (bh)1/2.
The base and height of the triangle are given as follows.
b = 5
h = 3 3/4 or 15/4
Plug these values into the above formula and solve.
A = (bh)1/2
A = 5(15/4)1/2
A = 75/4 * 1/2
A = 75/8
Answer:
The area of the triangle is in² or
in².

Answer:
Option C is correct.
Step-by-step explanation:
Given the dimension of the surfaces i.e length, width and height of podium. we have to calculate the surface area of the victory podium.
As Surface area of cuboid is 2(LW+WH+HL)
In the given figure, the upper cuboid has dimension
L=2.5 ft. , W=1.5 ft, H=1.5 ft
The upper face is occuring twice therefore it must be subtracted to find the area
Dimensions of lower podium are
L=7.5 ft. , W=1.5 ft, H=1.5 ft
Now, Surface area of podium included bottom is
19.5+49.5-3.75=65.25 square feet.
Hence, option C is correct.
