Answer:
84.87sq ft
Step-by-step explanation:
Let ABC be the triangle and AD be the perpendicular on BC such that BD=DC=7ft.
Now, it is known that 
Now, in triangle ADC, we have
Now, area of the triangle=
=
=
Thus, area of the building is 84.87sq ft.
Answer:
Terms=7a,3 Variables=a Coi=7 Constants=3
Step-by-step explanation:
Terms are the things you use in the equation.
Terms=7a, 3
Variables are the letters next to numbers
Variables= a
Coificents are numbers next to the variable.
Coi=7
Constants are numbers by themselves
Constants=3
Answer:
Around 100,i.e. 105
Step-by-step explanation:
In the given cube
Length of the cube = 7 unit cells
Breadth of the cube = 3 unit cells
Height of the cube = 5 unit cells
Therefore the number of unit cubes required to make such big cube is nothing but the volume of the big cube = length*breadth*height
⇒Number of cubes used to make that big cube= 7*5*3
= 105
Hence, option D (around 100) is the correct answer
You would need 13/14 12in rulers to make it the size of the flag
