Answer:
3 3/4
Step-by-step explanation:
First: 1/4 x 15/1 = 15/4
Second is to simplify: 15/4 equals 3 3/4
because its isosceles so 9+9=x²
and x equal
2√3
The area of that square would be 121 cm^2 because :
area of square = length(width)
= 11(11)
= 121
Then you also have to square the units(cm). So the final answer would be 121 cm^2 (the " ^ "represents the exponentiation)
