Answer:
1) Change the length of side AB to 2 feet
Step-by-step explanation:
Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.
To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:
We will assume AB is unknown.
PR = 7.5 ft
AC = 2.5 ft
PQ = 6 ft
Plug in the values into the equation
Cross multiply
Divide both sides by 7.5
The architect should change the length of AB to 2 ft
Answer:
The total surface area of the given shape is = 253.5
Step-by-step explanation:
Side of the square = 6.5 in
We know that area of the square is given by the equation
⇒ A =
Put the value of a in above equation we get
⇒ A = 6.5 × 6.5
⇒ A = 42.25
We know that the given shape has 6 surfaces so total surface area of the given shape is given by
⇒ = 6 × 42.25
⇒ = 253.5
Therefore the total surface area of the given shape is = 253.5
