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.
