The answers you have fix for the first section are a and b, you just missed one line for each. The answers are:
a). WS, ZV, YU
b). WX, VU, ST
Answer:
Step-by-step explanation:
To find the area of a rectangle you use the formula: A= lw
** l is length and w is width
For figure A and C, they're rectangles, so you multiply the length and the width to get the area:
Fig. A )A=lw
= (4)(4)
= 16
For figures B and D, you use the formula: A= bh/2
**B is the base and h is the height
Fig. D) A=bh/2
= 6(4)/2
= 12
Hey there! How is your day going?
Sorry if I'm a bit rusty here, math isn't my best subject, necessarily.
If you will notice ABCD is similar in size to EFGH, but the measurements are multiplied by 5. So, all we need to do is multiply the area of ABCD by 5.
35 x 5 = 175
So, your answer is 175 ft²
I hope this helped you, as it has helped me learn a different way to find the area of a rectangle. And I hope you have a very nice day!

x^2 + 10x + 4 = 0
you can use the quadratic formula to solve:
a = 1, b = 10, c = 4
x= −b ± √b^2 −4ac / 2a
x = -10 ± √(10)2 − 4(1)(4) / 2(1)
x = -10 ± √84 / 2
x = -0.42 or -9.58
