Find the dimensions of a rectangular building with a perimeter of 110 meters if the length is four
tiny-mole [99]

Answer:

b = 11 m

l = 44 m

Step-by-step explanation:

l = 4b (length is four times width)

Perimeter = 110 m

2 * ( l + b ) = 110

2 * (4b + b ) = 110

         2 * 5b = 110

                b = 110 / ( 2*5) = 11

b = 11 m

l = 4b = 4 * 11 = 44 m

lin and pazi are think of a number lins number is 7 more than pazi number the sum of the number is 49 whats pazi number
Lesechka [4]
Lin's number = l
pazi's number = p

l = p + 7
p = p

p + 7 + p = 49

2p + 7 =  49

2p + 7 (-7) = 49 (-7)

2p = 42

2p/2 = 42/2

p = 21

l = p + 7

l = 21 + 7

l = 28

pazi is 21 years old, Lin is 28 years old

hope this helps
