The length of a rectangular garden is 30 yards more than the width. the perimeter

Lets use the distributive property and to this...

Fist 8×53 might be hard so lets break it to (50×8)+(3×8)

⇒400+24

⇒424

And we still have the 125 whcih we have to multiply with 424

Here again we do it the same way but its more packed with steps.

424×125

⇒[(400×100+400×25)+(20×100+20×25)+(4×100+4×25)]

⇒[(40000+10000)+(2000+500)+(400+100)]

⇒[(50000)+(2500)+(500)]

⇒50000+2500+500

⇒50000+3000

⇒53000
