Step-by-step explanation:
similar triangles.
that means there is one common factor to transform the lengths of all lines from one triangle to the other.
it looks to me DF is the longest side in DEF, and that would make it associated to BC of ABC.
so, the factor is then
BC = DF×f
24 = 12×f
=> f = 2
so, EF then is associated to AC.
AC = EF × f
18 = EF × 2
EF = 18/2 = 9
Answer:
Area of the gym floor = 100.8 square meters
Step-by-step explanation:
Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap
Area of rectangle A = 105 square meters
Area of rectangle B = 8.4 square meters
Area of the overlap = 
= 
= 12.6 square meters
Area of the gym floor = 105 + 8.4 - 12.6
= 100.8 square meters
Therefore, area of the gym floor is 100.8 square meters.
