Answer:
Area = 960 cm^2
Step-by-step explanation:
Perimeter (P) = 2 (l + w)
P = 2l + 2w
Let the length be 5x
Let the width be 3x
From the question, P = 128.
Therefore:
128 = 2l + 2w
Divide both sides by 2.
l + w = 64
Recall we said:
l = 5x
w = 3x
So then:
5x + 3x = 64
8x = 64
Divide both sides by 8
x = 64/8
x = 8.
Since x = 8
Length = 5x = 5*8 = 40cm
Width =3x = 3 * 8 = 24cm
Area of a RECTANGLE:
Area = length * width
Area = 40 * 24
Area = 960 cm^2
To answer, change the 6 into a fraction
6 x 6/6 = 36/6
36/6 + 4/6 = 40/6
Simplify
40/6 = 6 4/6, or 6 2/3 (simplified)

Answer:
The first one
Step-by-step explanation:
the X values are all diffrent
When measuring the weight or mass of a small object, you can use a scale or a balance. You can use a scale to measure ounces and pounds. When measuring units of capacity in cooking, you can use measuring cups and measuring spoons.
