Answer:
Width=6.5 cm
Length=12 cm
Step-by-step explanation:
Step 1: Express the lengths and widths
Width=w
Length=l, but 1 cm less than twice the width=(2×w)-1=2 w-1
Step 2: Solve for the length and width
A=L×W
where;
A=area of the photograph
L=length of the photograph
W=width of the photograph
In our case;
A=91 cm²
L=2 w-1
W=w
91=(2 w-1)w
2 w²-w=91
2 w²-w-91=0, is a quadratic equation
solve for w
w={-1±√(-1²-4×2×-91)}/(2×2)
w=(-1±27)/4
w=(27-1)/4=6.5, or (-1-27)/4=-8
Take w=6.5 cm
L=(2×6.5)-1=13-1=12 cm
Width=6.5 cm
Length=12 cm
Answer:
Assuming that you are listing the length of each side of the figure, we can add the values together. The perimeter is 16 cm.
Step-by-step explanation:
6+2+2+6=16 cm

</u>Part <u> x</u> = <u>70</u>% 100·x = 100x 80·70 = 5600
Whole 80 100%
<u>100x </u>= <u>5600</u>
100 100
x = 56
