The perimeter of RSTU can be calculated alone without the help of MNPQ. It would be just 2(4) + 2(3) = 14 units. However, it would be much sensible if you want to find the parameter of the bigger rectangle. Since they are similar, you could use ratio and proportion.
(length/width)∨MNPQ = (length/width)∨RSTU
(x/9) = (3/4)
x = 6.75 units
Thus the perimeter of MNPQ is 2(6.75) + 2(9) = 31.5 units
Answer:
96 square units
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying height × base
The height given for this parallelogram is 12 units and base is 8 units
12 × 8 = 96 square units
Answer:
49 cm²
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the length of the side, thus
s³ = 343 ( take the cube root of both sides )
s =
= 7, thus
area of base = s² = 7² = 49 cm²
The answer is 296.
explanation-
1 meter = 100 centimeters
so 3 meters would equal 300 cm
now 300-4 = 296.
which would be how much she used
