Answer;
64
Step-by-step explanation:
eee 4*4*4=64
sorry if im wrong, since it's a square than all the sides are the same, if it is a 3d CUBE then the area is 64 but if you're talking about a 2d square then its 16
Yo sup??
Lenght of two side will be equal to 20 in as its an isoceles triangle.
The third side will be
x^2=b^2+h^2 (by pythagoreas theorem)
=9^2+9^2
x=9√2 in
Therefore the perimeter is = 9+9+9√2
=9√2(√2+1) in
Hope this helps.
