Step-by-step explanation:
Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be
cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
This is true because:
-57+27=-30
Answer:
7.5 units squared
Step-by-step explanation:
Equation for solving the area is A = 1/2h(b1 + b2).
The bases here have a length of 4 and 1, so we add them together. The height is 3, so our equation is 1/2 * 3(5) = 7.5
