P = 58 inches;
l = 3 + w ; where l = the length ; w = the width ; P = the perimeter ;
But, P = 2l + 2w ;
Then. 58 = 2( 3 + w ) + 2w ;
58 = 6 + 2w + 2w ;
58 = 6 + 4w ;
52 = 4w ;
w = 52÷4;
w = 13 inches ;
l = 3 + 13 = 16 inches .
$80
She must draw out more than the purchase price of $69

Answer:
52
Step-by-step explanation:
Total Number of students :
Stage 3 : 380
Stage 4 : 240
Stage 5 : 110
Total = (380 + 240 + 110) = 730
Number of samples required = 100
Number of key stage 3 students required :
(Key stage 3 / total) * number of samples
(380 / 730) * 100
= 0.5205479 * 100
= 52.0547
= 52
