Answer:
<u>416 square centimeters</u>
Step-by-step explanation:
Formula for finding area of a trapezoid :
<u>A = 1/2 x (a + b) x h</u>
- a and b = parallel sides of the trapezoid
- h = height of the trapezoid
Solving :
- A = 1/2 x (38 + 14) x 16
- A = 8 x 52
- A = <u>416 square centimeters</u>
Answer:
y = 7/18
Step-by-step explanation:
6 ( -3y + 2) - 5=
-18y + 12 - 5 =
-18y + 7 =
-18y = -7
y = 7/18
Answer:
surface area = 136 m^2
Step-by-step explanation:
The prism has 5 faces.
Faces 1 and 2: The front and back faces are two congruent triangles with base 6 m and height 4 m.
Face 3: The bottom face is a rectangle with length 7 m and width 6 m.
Faces 4 and 5: The left and right inclined faces are two congruent rectangles with length 7 m and width 5 m.
area = area of faces 1 and 2 + area of face 3 + area of faces 4 and 5
area of triangle = bh/2
area of rectangle = LW
area = 2 * 6 m * 4 m / 2 + 7 m * 6 m + 2 * 7 m * 5 m
area = 24 m^2 + 42 m^2 + 70 m^2
area = 136 m^2
Answer: surface area = 136 m^2
