Answer:
Area 36 square units; formula area = 1/2 x base x height
Step-by-step explanation:
Area = 1/2 x base x height
You're not given the base or the height, but this is an isosceles rt. triangle and the base and height are both opposite equal angles (45 degrees) so those two sides are equal to each other, too.
Lets say the base length is b. That is the height length too, then
From Pythagoras, we have
b² + b² = 12², so 2b² = 12² = 144.
So b² = 72.
So base = √72. But the height is the same length, so height = √72.
So area = 1/2 x base x height = 1/2 x √72 x √72 = 1/2 x 72 = 36 square units

Answer:
Actual distance is 4500 cm (45 m).
Step-by-step explanation:
A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.
scale =
It is in the form of a ratio.
From the question, Distance on map = 4.5 cm,
scale = 1 : 1000
=
scale =
Let the actual distance be represented by d.
So that,
=
⇒ d = 4.5 x 1000
= 4500
d = 4500
The actual distance is 4500 cm (45 m).
