Answer: √58 cm or 7.62 cm
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c². Since we are given the lengths of a and b, we can plug them into this formula to find the length of the hypotenuse.
7²+3²=c²
49+9=c²
58=c²
c=√58 or 7.62 cm
I think it would be A.
Maybe not because they are all negatives.
$30, because basically, it's -100, +100, -30.
P = 2(L + W)
P = 276
L = 76
276 = 2(76 + W)
276 = 152 + 2W
276 - 152 = 2W
124 = 2W
124/2 = W
62 = W <=== the width is 62 yds
