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.
Twenty three times a number.

Top and bottom
find area of each plank top and m ultiply by 2 then by number of planks
8*3*2*12 (dozen=12)
576
he needs to varnish 576 ft^2
how many 125's are at least 576 (round up since he can't buy fractios of a pint probably)
125x<u>></u>576
dividee both sides by 125
x<u>></u>4.608
x=5
5 times 3.5=17.5
a. 576 ft^2
b. $17.5
