<h3>
Answer: (2, 12)</h3>
=================================
Explanation:
The translation rule is T(x,y) = (x-5, y+10) meaning we shift P 5 units to the left and 10 units up to go from P(2,-4) to P ' (-3, 6)
x = 2 ---> x-5 = 2-5 = -3
y = -4 ---> y+10 = -4+10 = 6
Apply the same idea to the point (7,2) to get the following two values
x = 7 ----> x-5 = 7-5 = 2
y = 2 ---> y+10 = 2+10 = 12
3 x 7 = 21
3 x 7 = 21
3 x (9-3-3) = 3 x (9-6) = 3 x 3 = 9
21+21+9 = 51
51 meters
If the dimensions of the prism are doubled the surface area of the enlarged prism is 640 cm²
<h3>Surface area of a rectangular prism:</h3>
where
h = height
l = length
w = width
Therefore, if the dimension of the prism are doubled the new dimension will be as follows:
l = 5(2) = 10 cm
w = 2(2) = 4 cm
h = 10(2) = 20 cm
Therefore,
surface area = 2(10 × 4) + 2(10 × 20) + 2(20 × 4)
surface area = 2(40) + 2(200) + 2(80)
surface area = 80 + 400 + 160
surface area = 640 cm²
