The length of the rectangle is 5cm more than its width when its area is 150cm²

Answers

Width = 5

Lengtg = 10

Step-by-step explanation:

REPRESEBTATION :

Let x be the width

Let x+5 be the length

Area = 50

Mathematical Sentence:

Since Area = Length x Width

Area = x(x+5)

50 = x(x+5)

x(x+5)=50

Standard Form of Quadratic Equation:

x²+5x-50=0

Solution:

x²+5x-50=0 ➡️ (x-5)(x+10)=0 ➡️ x-5=0; x+10=0

x = 5 or x = -10

(since there's no such thing as a negative width or length, kaya we will use x = 5)

Width = x ➡️ x=5

Length = x+5 ➡️ 5+5=10

Final Answer:

The width of the rectangle is 5, while the length is 10

The length and the width of perimeter is 25

L, W= A÷?=?

P= ?m+?m+?m+?m

Equation:

A= L=(?), and W=(L-5)

P= L+L+W+W

Solution:

A= 50cm²

L, W= A÷?=?

L, W= 50÷10= 5

L= 10

W= (10-5)

A= L= 10 W= (10-5)

L= 10m

W= 5m

P= L+L+W+W

P= 10+10+5+5

P= 30m

L= 10m

W= 5m

P= 30m

that's I know

length(15) width(10)

Explanation:

rectangle=L x W

15x10=150

answer:

Step-by-step explanation:

L=x+5

W=x

A=50

A=lw

50=x(x+5)

x²+5x-50=0

A answer?

I don't think if I'm correct or incorrect...?

1. (n) (n+2)=195

n^2 + 2n - 195 = 0

2. (x) (x+5)=50

x^2 + 5x - 50 = 0

3. incomplete problem

4. (h) (h+3)=75

h^2 + 3h - 75 = 0

The length is 15 and the width is 10
