Divide the hexagon into 6 congruent triangles. The cut lines will start at the center and extend out to the vertices. See attached image to see what I mean. Each of the six triangles are the same, so we need to find the area of one triangle and then multiply that result by 6. Each triangle has a base of 5 cm and a height of 4.3 cm, so the area of a single triangle is A = base*height/2 = 5*4.3/2 = 10.75 square cm

Multiply this by 6 and we get 6*10.75 = 64.5 square cm which is the final answer (choice A)

The maximum height of a vehicle that can safely pass under a bridge is 12 feet 5 inches. A truck measures 162 inches in height.

AlladinOne [14]

Height of the truck =m 162 inches Height of the bridge under which vehicles pass = 12 feet 5 inches = (12 * 12) + 5 inches = 144 + 5 inches = 149 inches We arrived at the above deduction from the fact that 1 feet is equal to 12 inches. Now Difference in height of the truck and the bridge is = 162 - 149 inches = 13 inches So the truck is 13 inches taller than the maximum height of the bridge. The correct option among all the options that are given in the question is the second option or option "B". I hope it helps you

The length of a rectangle is 2 feet less than twice the width. The area of the rectangle is 180 feet squared. Find the length an

Ksenya-84 [330]

Answer:

Width=10

Length=18

Step-by-step explanation:

The length is 2 feet less then twice the width

Let the width be x.

Then the length is 2x -2 based on the given information. Use this to make an equation since it is known that the area is 180feet squared.

x(2x-2)=180

2x^2 - 2x - 180 = 0

2( x^2 - x - 90) = 0

We now have a factorable quadratic.

2(x+9)(x-10)=0

So by zero product property, x=-9, x=10 Since a measure cannot be negative, -9 is an extraneous solution.

So x=10

Then the width is 10 and the length is 18

Hope this helps! Let me know if it is correct!
