Question

How many segments $xunits$ long, are needed for the perimeter of each figure? Are the shapes same? Are their perimeters same?

Answer 1

Step 1: Number of segments required for the perimeter

Number of $xunits$ segments required for part (a) $=8$

Number of $xunits$ segments required for part (b) $=8$

Step 2: Comparing the shapes

Part (a) has a length of $3xunits$ and a breadth of $xunits$

Thus, it is a rectangle

Part (b) has a length of $2xunits$ and a breadth of $2xunits$

Thus, it is a square.

No, the shapes are not same part (a) is rectangle and part (b) is square.

Step 3: About perimeters

Yes, the perimeters are same as both required same number of segments.
