Question

The rectangle is 22cm along the base

The sides of this rectangle are in the ratio 4 : 3. If the longest side is 22 cm, what is the rectangle's perimeter?

(Remember that perimeter is the sum of all sides.)

Answer 1

x / 22 = 4 / 3 ;
x = ( 22 * 3 ) / 4 ;
x = 66 / 4 ;
x = 16,5 ;
P = 2*22 + 2*16,5 ;
P = 44 + 33 ;
P = 77 .
