I hope this helps. : )
56 because i just took the test ps this is wrong i just need the points
1) Divide 3/4 by 1/2. Remember how to divide fractions. Switch the problem into a multiplication problem.
<span>3/4 x 2/1 = 3/2 (so you could only have 1 and 1/2 servings with 1/2 pound of chicken in each serving. </span>
<span>2) Set up a little algebra problem. Let x = the multiplier of the original 3/4 pounds of chicken needed to make two full servings with 1/2 pound of chicken in each. </span>
<span>(3/4)x = 2(1/2) (Found this online V(0-0)v)</span>

g=84/21
g=4
The answer is B
Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32
