Firstly, we will draw diagram
we will draw line qq'
which will make mqq'n as parallelogram
and we know that opposite sides of parallelograms are always equal
so, we get
we are given
mq=42
so,
we can see that q' lies on np
so, we can write as
we are given
np=112
so, we can plug these values
now, we can see that
triangle qpq' forms isosceles triangle
so, we get
so,

Answer:
24 blocks will be needed to make the tower that is 4 feet high
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ Charlie knows that 3 blocks are needed to make a tower that is
0.5 foot high
∵ He needs to make a tower that is 4 feet high
→ By using the ratio method
→ Blocks : height (ft)
→ 3 : 0.5
→ x : 4
→ By using the cross multiplication
∵ x × 0.5 = 3 × 4
∴ 0.5x = 12
→ Divide both sides by 0.5 to find x
∵ =
∴ x = 24
∵ x represents the number of blocks
∴ 24 blocks will be needed to make the tower that is 4 feet high
