The scale ratio of a point A to another point B is the division of the length of B by the length of A. The area of the room is approximately 266.67 square feet.
Given that:
--- length of rectangle
--- width of rectangle
Divide by 12 to convert the dimensions to feet
means that the dimension of the room is 40 times the dimension of the rectangle.
So, we have:
The area of the room is:
So, we have:
The area of the room is 266.67 square feet

Multiply by 4/3 on both sides :
3/4a*4/3=24*4/3
a=96/3
a=32
Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
Answer:
<h2>5 units</h2>
Step-by-step explanation:
A right angled triangle is a triangle that has one of this angles to be 90°. According to the ΔABC, the angle at B is 90°.
Area of a triangle = 1/2 * base * height
According to the diagram shown, the base is BC and the height is AB which is the required side.
Area of the triangle = 1/2 * BC * AB
Given area of the triangle = 10 square units
BC = 4 units
AB is the required length.
Substituting this values into the formula above;
10 = 1/2 * 4 * AB
10 = 2AB
Dividing both sides by 2
2AB/2 = 10/2
AB = 5 units
Hence the length of AB is 5 units.
