HELP!!!!!!!!!! WILL GIVE BRAINLY!!!!!!!
atroni [7]

Answer:

141in^{2}

Step-by-step explanation:

Area of a trapezium = \frac{h}{2}(a + b)

h = height

a and b = upper and and lower lengths

Area of a trapezium = \frac{9}{2}(10 + 16)

 =  \frac{9}{2} × 26

 = 117in^{2}

Area of a triangle = \frac{1}{2} × base × height

 = \frac{1}{2} × 6 × 8

 =  \frac{1}{2} × 48

 = 24in^{2}

Total area = Sum of the areas of both the shapes

 = 117 + 24

 = 141in^{2}

Fred and Sue want to fence in a rectangular area in their yard for a vegetable garden. Suppose that they have 30 feet of fencing
larisa [96]

Answer:

a=35x−x^2

Step-by-step explanation:

Having  

70 ft of fencing with a  

width of x

feet and knowing the perimeter of a rectangle is  

p=2w+2l

we can state the length of the garden as:

70=2x+2l

and solving for  l

we know the length with be:

2l=70−2x or l=35−x  

And then knowing the formula for the area of a rectangle is  

a=w⋅l

we can write the equation as:

a=x⋅(35−x)a=35x−x^2
