Answer:
66.341 Feet
Step-by-step explanation:
length 819
width 818
(Length x width)
divide both by 100.5
819/100.5
818/100.5
8.14925373134
8.13930348259
round
8.15
8.14
length times width
8.15*8.14
66.341
Answer:
1100 square inches
Step-by-step explanation:
Formula: LxW
<u>Smallest rectangles</u> area: 5*20=100= 1 rectangle
there are 2 smal rectangles so= 100*2=200
<u>Medium rectangles</u> area: 5*30=150
There are 2 so= 150*2= 300
<u>Biggest rectangle:</u> 30*20= 600
Total Area: 200+300+600= 1100 square inches
SUM: x + y = 288
DIFFERENCE: + <u>x - y = 48 </u>
2x = 336
x = 168
SUM: x + y = 288 → (168) + y = 288 → y = 120
Answer: 120, 168
10(x2) = 70(x)
10x2 - 70x
10x = 70

x = 7 </span>
