Surface area = 2(6*3) + 2(6*2) + 2*(2*3) = 36+24+12 = 72 cm^2
Answer:
Step-by-step explanation:
a=10 (4,0,2,4,3,1,2,3,1,4)
b=4 (7,5,6,9)
c=6 (13,13,13,10,13,12)
d= 5 (17,16,17,17,16)
e=6 (21,23,20,20,21,23)
- Total time=5h
- Time devoted for mathematics and science=2h
Let Time devoted for others be x
<span>Let the wall's length be y. So the fence parallel is also y.
We form the equation;
2x + y = 240
Now the area A is x*y, which is given as 5500.
We have 2 equations with 2 variables. Solve them and get the answer.
xy = 5500
2x + y = 240
Y = 5500/x
2x + (5500/x) = 240
2x^2 - 240x + 5500 = 0
x^2 - 120x + 2750 = 0
Work out the value(s) of x from above. </span>
