Question

Edward has 2 rectangular vegetable gardens. One measures 230 centimeters by 125 centimeters and the other measures 110 centimeters by 50 centimeters.If Edward wants to put a fence around both, how much fencing does he need to buy.

Edwards brother also wants to put up a fence around his garden that is 110 centimeters by 40 centimeters.

What is the difference in the length of fence that each will purchase.


I just don't understand the problems like these. Please help me

Answer 1

i’m bad at explaining so sorry in advance
ok so for the first one you have to find out the perimeter for both vegetable gardens.
so it would be 230x2=460 and 125x2=250 forever the first vegetable garden. you add up 460+250=710 and 710 centimeters is how much fencing he wants to buy!
same with the second garden, 110x2=220 and 50x2=100 220+100=320 and so he wants to buy 320cm of fencing for his second veggie garden

for the second question they’re still asking for perimeter so 110x2=220 and 40x2=80 220+80=300 so Edwards brother wants to get 300cm of fencing

the fact that i know this much doesn’t make me any smarter so i have no clue how to answer the 3rd question
