Answer:
57.1
Step-by-step explanation:
Perimeter Formula: P = 2l + 2w
Simply plug in what we know and solve:
269.4 = 2l + 2(77.6)
269.4 = 2l + 155.2
114.2 = 2l
l = 57.1
305 to the nearest ten is 310.
100 / 9
They both equal 11.11
(70/21)^2 * 8^3 * (1/2^9)
7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
