Answer:
40
Explanation:
The shape has 6 sides a,b,c,d,e,f
The perimeter is the sum of the sides
P = a+b+c+d+e +f
4 of the sides add to 195 a+b+c+d = 195 Replace in the equation
P = 195 +e+f
We know that e and f are equal
P = 195+f+f
P = 195+2f
The perimeter is 275
275=195+2f
Subtract 195 from each side
275 -195 = 195+2f-195
80 = 2f
Divide by 2
80/2 = 2f/2
40 =f
The other 2 sides are 40 ft each
