⇔
,
= 1
Thus
y² ← substitute values into expression
= × 4² =
× 16 =
and denominator
= 1 × 4³ = 1 × 64 = 64
Now dividing
÷ 64
= ×
( cancel 16 and 64 )
= =
Answer:
<em>The dimensions of the tabletop: Length= 67.976... inches and Width= 33.988... inches and the perimeter will be 203.929... inches.</em>
Step-by-step explanation:
Suppose, the width of the rectangular tabletop is inch.
As the tabletop has a length that is twice it’s width, so the length will be: inch.
The tabletop measures 76 inches on its diagonal.
<u>Formula for length of diagonal of rectangle</u>:
So, the equation will be..........
Thus, the width of the tabletop is 33.988... inches and the length will be: (2×33.988...) = 67.976... inches.
The perimeter will be: 2(33.988...+ 67.976...) inches = 203.929... inches.
