The dimensions of the scale drawing of a rectangle are 8cm and 11cm. If the scale factor is 4, what is the length of the origina
1 answer:
Answer:
Length of the original rectangle is 2.75 cm
Step-by-step explanation:
The dimensions of the scale drawing of rectangle are 8 cm and 11 cm respectively.
This implies that the width of the rectangle is 8 cm while the length of the rectangle is 11 cm.
The scale factor is given as 4. This means that the dimensions of the original rectangle are 1/4 times the given dimensions.
So the length of the original rectangle =

Answer:
15 feet
Step-by-step explanation:
Given that,
The cat is 12feet above the ground, and Peter has to put the base of his ladder 9 feet away from the tree because of mud.
If we consider a right-angled triangle, in which the height is 12 feet, base is 9 feet.
We need to find how long does the ladder need to be in order to reach the cat i.e. the hypotenuse of the triangle.
We can use the Pythagoras theorem to find it.
So, the ladder must be at a distance of 15 feet in order to reach the cat.
