Perimeter: Locate the Absent Side Lengths

Perimeter: Locate the Absent Side Lengths – Example 1:

The perimeter of a square \(= 4 × side →\) \(4 × x= 48 →\) \(x=\frac{48}{4} = 12\) \(→ x=12\)

Perimeter: Locate the Absent Side Lengths – Example 2:

Find the missing side of the shape.

Perimeter \(=50. x=\)___

Solution:

The perimeter of a rectangle \(= 2 × (l + b)→\) \(2× (14+x)= 50 →28+2x=50 →2x=22 →\) \(x=\frac{22}{2} = 11\) \(→ x=11\)
