Answer:
83+11_
Step-by-step explanation:
Length (L): w + 3.5
width (w): w
Perimeter (P) = 2L + 2w
31 = 2(w + 3.5) + 2(w)
31 = 2w + 7 + 2w
31 = 4w + 7
24 = 4w
6 = w
Length (L): w + 3.5 = (6) + 3.5 = 9.5
Answer: width = 6 inches, length = 9.5 inches
The base's length is 8 and it's width is 7, so it's perimeter will be

. To find the lateral area you shoul multiply this with it's height. So,

(h is height).
Answer:
B
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find x
tan22° =
= 
Multiply both sides by x
x × tan22° = 203 ( divide both sides by tan22° )
x =
≈ 502.5 m → B
