Answer:
x= 16 ft.
Step-by-step explanation:
Let 'x' and 'y' are the lengths of the two pieces then:
1.) x + y = 36
2.) x : y = 4 : 5 cross multiply
3.) 5x = 4y
by solving the system of equations
x + y = 36
5x = 4y
we find
x = 16 ft
y = 20 ft
Answer:
Area = 22.3 m^2
Perimeter 27.4 m^2
Step-by-step explanation:
Perimeter = __ m
Area __ m^2
The area of the triangle is about 4.2,
The area of the square is 4,
The area of the semicircle is 14.1,
14.1 + 4.2 + 4 = 22.3
Area = 22.3 m^2
9.4 + 6 + 4 + 4 + 4 = 27.4
Perimeter = 27.4 m^2
Therefore the area of the shape is about 22.3 m^2 and the perimeter is about 27.4 m^2.
Answer:
you do Length x Width x height
8 3/8 x 6 x 8 1/4 = 414.56
hope this helps :-)
Answer:
First find the circumference by pi r squared.
The perimeter of the triangular end is 12 m, so the total rectangular area is
.. (12 m)*(8 m) = 96 m^2
There are two triangles with base 3 m and height 4 m, so their total area is
.. (3 m)*(4 m) = 12 m^2
The surface area of the figure is the sum of these
.. 96 m^2 +12 m^2 = 108 m^2
