Answer:
Length 34 cm
Width 8 cm
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
The perimeter of rectangle is equal to
P=2(x+y)
P=84 cm
so
84=2(x+y)
42=x+y ----> equation A
x=4y+2 -----> equation B
substitute equation B in equation A and solve for y
42=(4y+2)+y
5y=42-2
y=40/5=8 cm
Find the value of x
x=4y+2 ----> x=4(8)+2=34 cm
The dimensions are
Length 34 cm
Width 8 cm
Answer:
A=28.13 Sq Ft
Step-by-step explanation:
Given that the length of the garden = 4.5 ft
Breadth of the garden = 6.25 ft
Area is given by the formula
A=length x breadth
A=4.5 x 6.25 sq ft
A= 28.125 sq ft
Here if we round the area to the nearest hundredth, the area will be
A=28.13 Sq Ft
6.2 is not a whole number
150/3 = 50 = a whole number
25 and 13 are whole numbers.
