How do you fin perimeter and area?

Answer 1

The perimeter of a rectangle with 6 inches by 4 inches is (6 + 4) x 2 = 20 inches This is the same as 6 + 6 + 4 + 4 = 20 inches (2 sides and 2 ends).

The area of the same sized rectangle is 6 x 4 = 24 square inches (or 24in2 is the same answer, written in a different way).

Answer 2

Perimietr is twice the length plus twice the width.

Algebraically

P = 2( l + w) ( in the given units of length)

Area is the length multiplied to the width

Algebraically

A = l X w

More ususally and correctly sjown as

A = lb . ( in the given 'square units' on length )
