Answer:
40 square metres
Step-by-step explanation:
The shaded region is of a triangle, whose area is denoted by: A = (1/2) * b * h, where b is the base and h is the height.
Since the left figure is a square with side lengths 10, we know that the height of the triangle is also 10 metres. The right figure is a rectangle with length 4. Since the total base length of the entire figure is 18 and the base of the square is 10, then the width of the rectangle is 18 - 10 = 8 metres.
This width is also the base of the triangle, so b = 8.
Now plug these values into the equation:
A = (1/2) * b * h
A = (1/2) * 8 * 10 = (1/2) * 80 = 40
The area is 40 square metres.
3 -1i + 21i -7i2 now you have to fix the last factore because you have to change the imaginery i this would give you the answer of 3 - 1i + 21i +7 now add common factor which would give you the final answer of 3 +20i +7
Answer:
183.92 inch²
Step-by-step explanation:
To find the total amount of wrapping paper needed, you must find the Surface Area of the box.
Surface area of a rectangular prism is: A = 2(<em>wl</em> + <em>hl</em> + <em>hw</em>)
w = width = 3.8
h = height = 9.5
l = length = 4.2
Plug in the corresponding numbers to the corresponding variables.
A = 2(<em>wl</em> + <em>hl </em>+ <em>hw</em>)
A = 2((3.8 * 4.2) + (9.5 * 4.2) + (9.5 * 3.8))
Simplify.
A = 2((15.96) + (39.9) + (36.1))
A = 2(15.96 + 39.9 + 36.1)
A = 2(91.96)
Multiply.
A = 183.92
183.92 inch² is your answer.
