A = LW
A = 320
L = 5W
320 = W(5W)
320 = 5W^2
320/5 = W^2
64 = W^2
sqrt 64 = W
8 = W
L = 5W
L = 5(8)
L = 40
so the length (L) = 40 cm and the width (W) = 8 cm
P = 2(L + W)
P = 2(40 + 8)
P = 2(48)
P = 96 <=====
Hope this can help explain better got you. :)
I think the answer is N-4
Area of triangle = 1/2 x base x height.
Base = 14 cm
Height = 8 cm
Area = 1/2 x 8 x 14 = 56 cm^2
Correct option B
Answer:
the x would equal 25 as 5x2 is 10 + 16x25 - 84 is 0.
