Answer:
90 ft²
Step-by-step explanation:
Given the sides of similar figures in the ratio a : b, then
ratio of areas = a² : b²
Here ratio of sides = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the surface area of the new solid is 9 times the first
SA = 9 × 10 = 90 ft²
If you work with real numbers then the square root of - 1 CANNOT be defined.
If you work with complex numbers then the square root of - 1 is equal to the imaginary unit(which is symbolized as i)
