A^2 + b^2 = c^2 
3^2 + 8^2 = c^2 
9 + 64 = c^2 
73 =c^2 
take the square root of each side 
c= 8.544
 
        
        
        
The net would look like a square surrounded with four triangles, one on each side.

The maximum amount of money she wants to spend is $40
Her adult ticket costs $10
She will pay for the children’s tickets with the remaining money
Each child’s ticket costs $7
To find the number of children she can take we need to use this expression (40-10)/7
Mrs Herñàndez can take 4 children
