Area of a parallelogram = base x height
So, 10.5 x 7 = 73.5
Answer: The perimeter is 30ft.
Step-by-step explanation:
Let's define:
L = length of the longer side.
S = length of the shorter side.
P = perimeter
we know that for a common rectangle:
P = 2*S + 2*L
We aso know that:
L = 2ft + (1/3)*P
S = (1/10)*P
L = S + 9ft.
So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)
First, we can replace the third equation in the first equation, now we have a system with only two equations:
S + 9ft = 2ft + (1/3)*P
S = P/10
Now we can replace the second equation in the first equation, and get:
P/10 + 9ft = 2ft + P/3
Now let's solve this for P.
9ft - 2 ft = P/3 - P/10
7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)
(30/7)*7ft = P = 30ft.
The perimeter is 30ft.
Answer:
The correct answer is second option
380 square feet
Step-by-step explanation:
Area of composite solid = Base area + area of side rectangles + area of triangles
<u>To find the area of base</u>
Base area = length * width
= 10 * 10 = 100 ft²
<u>To find the area of side rectangle</u>
There are 4 rectangles with length 10 ft and width 6 ft
Area = 4 * area of one rectangle
= 4 * (10 * 6)
= 240 ft²
<u>To find the area of triangle</u>
Here base of triangle = 10 ft and height = 7 ft
Area of 4 triangles =4 * area of single triangle = 4 * (bh)/2
= 4 *(10 * 7)/2 = 140 ft²
To find the total area = Base area + area of side rectangles + area of triangles
= 100 + 240 + 140
= 380 square feet
The correct answer is second option
380 square feet
Answer:
the desired equation is y = -5x + 2
Step-by-step explanation:
The general slope-intercept form is y = mx + b. Here we know that m = -5 and b = 2, so the desired equation is y = -5x + 2.
