Question

The perimeter of a rectangle is 54cm. One side is xcm long and the other is 6cm longer. a) Form an equation involving x b) Solve the equation and write down the length of each of the sides

Answer 1

Answer:

answer is 21

Step-by-step explanation:

Total perimeter of rectangle is 54cm

Perimeter of rectangle =2×(l+b)

one side=x

second side =6 cm

2×(x+6)

=2x+12

then 2x =54-12=42

2x=42

x=42÷2

x=21

check

perimeter of rectangle =2× (l+b)

=2×(21+6)

=2×27

=54
