You are planning a deck along two sides of a pool. The diagram, which is not drawn to scale, shows how the deck is divided into three sections. The area of section 1 is 240 square feet. The area of section 2 is 64 square feet. The area of section 3 is 160 square feet. Find the perimeter around the entire deck. All measurements in the diagram are in feet.

wow i like the diagram !!

pratyush5 · Answer

lets begin with section 1 
here the length = 3x +6 and breadth = x therefore area will be ?

pratyush5 · Answer

no sorry lets take section 2

anonymous · Answer

okay

pratyush5 · Answer

then x multiplied by x = 64 right ?

anonymous · Answer

haha thanks @AravindG

pratyush5 · Answer

so x^2 = 64 
so x = sqrt(64) = ?

aravindg · Answer

i seriously recommend giving students questions like that ... makes study much more interesting and colourful ! ^_^

anonymous · Answer

haha 
and @pratyush5 okay so x=8?

pratyush5 · Answer

yes . now since x = 8 you can find the dimensions of all the three sides and the calculate the perimeter

anonymous · Answer

okay so I got 27 for 1and 20 for 3 but how do I do 2? just 8x8 or?
