Answer:
Perimeter of a rectangle = 2×(Length+Breadth)
(i) Length = 16.8 cm
Breadth = 6.2 cm
Perimeter = 2×(Length+Breadth)
= 2×(16.8+6.2) =46 cm
(ii) Length = 2 m 25 cm
=(200+25) cm (1 m = 100 cm )
= 225 cm
Breadth =1 m 50 cm
= (100+50) cm (1 m = 100 cm )
= 150 cm
Perimeter = 2×(Length+Breadth)
= 2×(225+150) =750 cm
(iii) Length = 8 m 5 dm
= (80+5) dm (1 m = 10 dm )
= 85 dm
Breadth = 6 m 8 dm
= (60+8) dm (1 m = 10 dm )
= 68 dm
Perimeter = 2×(Length+Breadth)
= 2×(85+68) =306
Answer:
The answer would be 10 + 30.
Step-by-step explanation:
This is because if the width is 10 you would do 10×3 which equals 30 and 30+10 equals 40 which is the perimeter of the rectangle.
Answer:
x=15, y=11 or x=11, y=15
Step-by-step explanation:
no quick or easy way to solve sys of eqns like this:
(1) x+y=26
and
(2) xy=165
rearranging (1),
y=26-x
substituting into (2),
x(26-x)=165
expanding n rearranging,
26x-x^2=165
x^2-26x+165=0
(x-15)(x-11)=0
x-15=0 or x-11=0
x=15 or x=11
y=26-15 or y=26-11
y=11 or y=15
so x=15, y=11
or x=11, y=15
