Answer:
The perimeter is found by multiply multiplying the length by 2 and adding it to the width multiplied by 2.
Perimeter = 2L +2W
The length is given as twice the width which would be written as 2W
Now you have P = 2(2w) +2w
The perimeter is given as 52 cm:
51 = 2(2w) +2W
Simplify:
51 = 4w +2w
51 = 6w
Divide both sides by 6:
w = 51/6
w = 8.5
The width is 8.5 cm
The length is 2w = 2*8.5 = 17 cm

According to the attachment
⠀
let AB be the ladder
BC be the distance between the ladder and wall
⠀
(a) We have to find ∠A by trigonometry formula
Here angle A is facing BC so it is perpendicular
and AB is the longest side so it is hypotenuse
(b)
AC is the distance from the upper end of the ladder to ground
we will find it by Pythagoras theorem
Answer:
2,4 and 7 do not form a triangle
Step-by-step explanation:
To form a triangle, knowing the 3 sides, then
The sum of any 2 sides must be greater than the third side
Consider 2, 4, 7
2 + 4 = 6 < 7
2 + 7 = 9 > 4
4 + 7 = 11 > 2
Since 2 + 4 < 7
Then these 3 sides would not form a triangle
