I know because I took the test
Answer:
(a) 94. (b) 85
Step-by-step explanation:
(a). the perimeter = 2l +2w ; l - length and W - width
: . 2l + 2(56) = 300
2l = 300 - 112
l = 188/2 =94m
(b) area = Lxw
8245 = 97w
w = 8245/97
= 85m
To simplify 174/216, all you do is keep dividing until the two numbers are <span>undivisable</span> by the same number. First I would divide by 2 to get 87/108. Then I would divide by 3 to get 29/36. 29 is a prime number therefore I can not divide by any whole number exact 1 and itself to get another whole number. Futhermore the answer is 29/36.
