Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
Answer:
r = 31.2
Step-by-step explanation:
Δ ACE and Δ BCD are similar, thus the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
40r = 1248 ( divide both sides by 40 )
r = 31.2
