30, you could just multiply both numbers, but it's also better to list out the factor until both match
Answer:
T.A. = 16√3 units²
Step-by-step explanation:
∵ The total area = the area of the four faces
∵ The four faces are equilateral triangles with side length 4
∵ Area of the equilateral Δ = 1/4 s² √3
∴ T.A. = 4 × 1/4 × 4² × √3 = 16√3 units²
Um I think the first one is non proportional and the 2nd one is proportional y is 5 times x the 5 might be a negative
should be 60 cm if not it's 11
