Answer:

4 cm ×12 cm

Step-by-step explanation:

To find the dimensions of the sticker, start by forming 2 equations for its area and perimeter.

Perimeter of rectangle= 2(length +breadth)

Let the length and breadth of the rectangle be L and B cm respectively.

2(L +B)= 32

Divide both sides by 2:

L +B= 16 -----(1)

Area of rectangle= length ×breadth

LB= 48 -----(2)

From (1): L= 16 -B -----(3)

Substitute (3) into (2):

(16 -B)(B)= 48

Expand:

16B -B²= 48

B² -16B +48= 0

(B -4)(B -12)= 0

B -4= 0 or B -12= 0

B= 4 or B= 12

Substitute into (3):

L= 16 -4 or L= 16 -12

L= 12 or L= 4

Thus, the dimensions of the sticker is 4 cm ×12 cm.

The ratio that comes next in the sequence is 8:23.

<h3 /><h3>Definition of a ratio</h3>

Ratio expresses the relationship between two or more numbers. It shows the frequency with which one value is contained in another value.

<h3 /><h3>How to determine the numbers that come next</h3>

Looking at the first ratio in the sequence, the number on the left increases by 1 in the second ratio. In the second ratio, the number on the left increases by 2 and for the third ratio. The difference between the third and fourth ratio is 1 for the number on the left. This shows that the sequence for the numbers on the left is 1, 2, 1. Thus the next number would increase by 2.

Looking at the first ratio in the sequence, the number on the right increases by 4 in the third ratio. In the fourth ratio, the number on the right increases by 4 when compared with the third ratio.  This shows that the sequence for the numbers on the right is an increase by 4.
