Answer:

32m

Step-by-step explanation:

{2(l + b)} * 18 = 1980

2(l + 23) = 1980/18

2(l+ + 23) = 110

l + 23 = 110/2

l + 23 = 55

l = 55 - 23

l = 32

Answer:

32m

Step-by-step explanation:

at first, we can calculate the perimeter by the formula :

total cost ÷ per cost

1980÷18

=110

thus we got the perimeter 110m

then, put the formula

P= 2( l + b )

110 = 2( 23 + b )

transfer the ×2 on RHS to LHS

110 ÷ 2 = 23 + b

55 = 23 + b

b = 55 - 23

b = 32

here's the answer.
