Question

Daniels garage is 8 ft long by 10 ft wide. His living room is twice as long, and twice as wide his garage. Daniels house is 3 times as long , and 4 times as wide his living room. What is the total perimeter of his house ?

Answer 1

length of living room = 2 x length of garage 
                               =2 x 8 ft
                               =16 ft 
width of living room  = 2 x width of garage
                              = 2 x 10 ft
                              = 20 ft
daniel house length =  3 x length of L.R
                             = 3 x 16 ft 
                             =48 ft 
daniel house width   = 4 x width of L.R
                              = 4 X 20 ft
                             = 80 ft 
preimeter of rectangle = 2[l + b] 
                                = 2[ 48 +80 ]
                               = 256 ft
perimeter of house = 256 ft
