Answer:
length = 8m
width = 4m
Step-by-step explanation:
The perimeter of a rectangle is the formula: P = 2w + 2l, where 'w' is equal to the width and 'l' is equal to the length. In this case, the width can be expressed as 'w' and the length, which is '4 meters longer than its width' would be 'w +4'. So, when you put these expressions into the equation:
P = 2w + 2(w +4)
P = 2w + 2w + 8 or 4w + 8
Since perimeter = 24m, plug it in and solve for 'w':
24 = 4w + 8
Subtract 8 from both sides: 24 - 8 = 4w + 8 - 8 or 16 = 4w
Solve for w: w = 4m
Solve for l: l = w + 4 or 4+4, so l = 8m
Because 34.4567 is closer to 34.46 than to 34.45, so the answer is 34.46.

Conclusion:
Step-by-step explanation:
Given
Two similar quadrilaterals
To determine
x, y, and z
Given that the two quadrilaterals are similar,
so their corresponding ratios will be:
x/10 = 5/4
x = 5/4 × 10
x = 50/4
x = 25/2
x = 12.5
Thus, the value of x = 12.5
To determine the value of y, the corresponding ratio such as
y/4 = 8/10
y = 8/10 × 4
y = 32/10
y = 16/5
y = 3.2
Thus, the value of y = 3.2
To determine the value of z, the corresponding ratio such as
z/5 = 15/x
as x = 12.5, so substitute x = 12.5
z/5 = 15/12.5
z = 15/12.5 × 5
z = 75/12.5
z = 6
Therefore, the value of z = 6
Conclusion:
Answer:
105 cm squared
Step-by-step explanation:
15×6 to get the rectangle =90
then we have a triangle left so you do 15- 9 for the base =6 and multiply that by hight (6×5=30) and since it's a triangle and not a square we have to divide that answer by 2 and we get 15. Add those together, we get 105. Hope that helped!
