The dimensions of the school yard is 58 m and 89 m.
<h3>What is rectangle ?</h3>
A rectangle is a polygon with four sides , It has opposite sides parallel and equal.
It is given that
A rectangular school yard has a perimeter of 294 meters
Perimeter of a rectangle is given by
P = 2(Length +Breadth)
294 = 2( L+B)
147 = L+B
Area of a rectangle is given by
L*B = 5162
B = 5162/L
L + 5162/L =147
L² -147L +5162 = 0
L² -58L - 89L+5162 = 0
L(L-58) -89(L-58)
L = 58 , 89
The dimensions of the school yard is 58 m and 89 m.

Answer:
2
Step-by-step explanation:
Given: a² +a +1= 0
Bringing a terms to the right-hand side:
1= -a² -a
-a² -a= 1
-a -a²= 1
1 -a -a²
= (-a -a²) +1
= 1 +1
= 2
