Answer:
x = 40
Step-by-step explanation:
Using similarity theorem, we have the following:

Solve for x

Cross multiply


Subtract 24x from each side


Divide both sides by -15
40 = x
x = 40
Answer:
Width = 160
Length = 110
Step-by-step explanation:
Perimeter is the sum of all the sides
They tell you that the length is 50 m shorter than the width
so L = W - 50
W = W
540 = W + W + W-50 + W-50
540 = 2W + 2(W-50)
540 = 2W + 2W - 100
540 = 4W - 100
640 = 4W
W = 160
L = 160 - 50
L = 110
Answer:
16.5
Step-by-step explanation:
=
=66/4=33/2=16.5
3.14(a2+ab)
3.14(3(2)+3(4)
3.14 +6+12
3.14+18
21.14 I think that's it sorry if it's not.
