Mr Lee has a board that is 6.45 feet long . He wants to cut it into three equal pieces . How long should each piece be

Each board should be 2.15 ft long

Step-by-step explanation:

6.45 ft ÷ 3 boards = 2.15 ft for each board

2.15 feet

Step-by-step explanation:

Since he wants 3 equal pieces, you need to divide the total amount (6.45 feet) by three.

6.45/3 = 2.15 feet

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
