Answer:
Step-by-step explanation:
The given figure is a trapezoid. The perimeter of a plane figure is expressed as the the distance around the figure. Therefore
Perimeter = a2 + b2 + a1 + b1
Perimeter = 4.7 + 5.8 + 8.5 + 6.89 = 25.89 feet
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the diagram,
a = 4.7 feet
b = 8.5 feet
h = 5.8 feet
Area = 1/2(4.7 + 8.5)5.8
Area = 1/2 × 13.2 × 5.8
Area = 38.28 feet²
Answer:
A
Step-by-step explanation:
Because if your going to divide a whole the whole number needs to be 3/1 so it A the mistake
The answer is attached. I hope this helps answer your question!
Take the area of the rectangle as a whole and subtract the triangle piece.
We know the dimensions of the triangle are 3x4 so you can multiply it out using the formula to find the triangle's area to get 6.
Then you calculate the area of the whole rectangle. 10x12=120.
Finally subtract the triangle from the rectangle. 120-6=114.
The Area of the deck is 114.
