Let w be the width
Then the length is 2w - 2
We also know that the perimeter is 62 cm. The perimeter is the distance around the rectangle, or 2w + 2(2w - 2).
So, 2w + 2(2w - 2) = 62
2w + 4w - 4 = 62
6w = 66
w = 11
So, the length is 2w - 2 = 2(11) - 2 = 22 - 2 = 20
Length = 20 cm
Width = 11 cm
Answer:
(a) -1^2 = -1
(b) 3 = 3
(c) 2(3) + 1 = 7
Step-by-step explanation:
Answer:
KL = 23
KM = 29
Step-by-step explanation:
By applying cosine rule in the given triangle KLM,
cos(∠M) = 
cos(52°) = 
cos(52°) = 
KM = 
KM = 29.24
KM ≈ 29
By applying sine rule,
sin(52°) = 
sin(52°) = 
KL = 29.24[sin(52°)]
= 23.03
≈ 23
KL = 23
