Answer:
272 yd²
Step-by-step explanation:
Surface area = base area + lateral area
= (10×10)+(8.6×10×2)
= 100+172
= 272 yd²
To find the width, divide the area by the length.
Width = 9/10 / 2/5
When dividing fractions flip the second one over and multiply:
Width = 9/10 x 5/2 = (9 x5) / (10 x 2) = 45/20 = 2 and 1/4 miles.

Answer:
x = -11
Step-by-step explanation:
I'm assuming it's an isosceles triangle so 32 + 2x = 10;

2x = -22
x = -11
2 X
