Perimeter: Locate the Absent Side Lengths

Perimeter: Locate the Absent Side Lengths: this Effortless Math guide explains the topic in plain language, shows how it works through solved examples, and gives you free practice to try immediately, so the idea sticks instead of staying abstract.

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)
