Given:
Bedroom is a rectangle with length 5 m and width 3 m.
Elena's bedroom door is 0.08 m.
Elena's bed measures 4 cm by 3 cm.
Scale of drawing is 1 to 50.
To find:
The width of door on the scale drawing.
Actual measurements of her bed.
Step-by-step explanation:
Scale of drawing is 1 to 50.
It means, the length of sides in drawing is of actual.
Elena's bedroom door is 0.08 m.
1 m = 100 cm
0.08 m = 8 cm
Door on the scale drawing
Therefore, the Door on the scale drawing is 0.16 cm wide.
Elena's bed measures 4 cm by 3 cm on the scale drawing.
Elena's bed actual measurements are
Therefore, the actual measurements of her bed is 2 m by 1.5 m.
Answer:
Option B is correct.i.e.,
Step-by-step explanation:
Given: Pyramid with equilateral triangle as base
Length of side of equilateral triangle = s unit
to find: height of equilateral triangle
Here we use a property of equilateral triangle.
Perpendicular from a vertex on a side and median of that side of a triangle is same in equilateral triangle.
All heights are of equal length. So, we just need to find one height or length of 1 altitude.
Figure of base triangle is attached
In Δ ABC
AB = BC = AC = s unit
AD is height
BD =
Now, In Δ ABD
using pythagoras theorem
BD² + AD² = AB²
Therefore, Option B is correct.i.e.,
