Area = 625 cm^2
Area = s^2
Diagonal = s*sqrt(2)
625 = s^2
s = sqrt(625)
s = 25 cm.
Diagonal = s*sqrt(2)
= 25sqrt(2)
=35.36 cm.
=35.4 cm.
I’ve attached my work....
Perpendicular is when the slope is. Flipped and opposite signs so that’s what I test for each line
Hope this helps!
2³ x 4³ = 2³ x (2²)³
2³ x 2²ˣ³ = 2³ x 2⁶ = 2³⁺⁶ = 2⁹
The answer is the first one (a)
