Answer: Width/length = 64 cm
Explanation:
Concept:
Here, we need to know the concept of rectangle perimeter.
A perimeter is either a path that encompasses/surrounds/outlines a shape.
P = 2 (w + l)
w = width
l = length
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
l = 96 cm
P = 320 cm
Given formula
P = 2 (w + l)
Substitute each value into the formula
320 = 2 (w + 96)
Divide both sides by 2
320 / 2 = 2 (w + 96) / 2
160 = w + 96
Subtract 96 on both sides
160 - 96 = w + 96 - 96
w = 64 cm
Hope this helps!! :)
