Answer:

Solution given:

perimeter of rectangle: 2(l+b)=2(3x-3+x-3)

  • =2(4x-6)=8x-12

perimeter of triangle: sum of all side

= 2x-1+2x-1+2x=6x-2

Since both perimeter are equal

8x-12=6x-2

8x-6x=12-2

2x=10

x=10/2

Sarah has a brother who is 5 years younger than herself and another brother who is 8 years younger than herself. She observes th
ELEN [110]

Answer:

Sarah is 13 years old

Step-by-step explanation:

Represent Sarah's age with S

Her first brother's age with F

Her second brother's age with B

So, we have:

From the first statement, we have:

S - F = 5 ---- (1)

From the second, we have:

S - B = 8 ---- (2)

The product of their ages is 40.

First, we make F the subject in (1) and B the subject in (2)

F = S - 5

B = S - 8

Their product is represented as follows:

F * B = 40

Substitute values for F and B

(S - 5) * (S - 8)=40

Open bracket

S^2 - 5S -8S + 40 = 40

S^2 - 13S + 40 = 40

Subtract 40 from both sides

S^2 - 13S = 0

Factorize:

S(S - 13) = 0

Split:

S = 0 or S - 13 = 0

But Sarah's age can't be 0 because she has two younger brothers.

So, we stick to

S - 13 = 0

Make S the subject

S = 13

<em>Hence, Sarah is 13 years old</em>
