Mark’s garden is a rectangle that is (4a+96)/(a+15) meters long and (4a+24)/(a+15) meters wide.

if mark decides to fence his garden, the total length of fencing material required would be *blank* meters. if he uses prebuilt fence sections that are 50 centimeters wide, he will need *blank* sections.

i have no idea

ℓ: (4a + 96)/(a + 15) 

w: (4a + 24)/(a + 15) 

p = 2 * { ℓ + w } 

p = 2 * { [(4a + 96)/(a + 15] + [(4a + 24)/(a + 15)] } 

p = 2 * { [(4a + 96) + (4a + 24)] / (a + 15) } 

p = 2 * { (4a + 96 + 4a + 24) / (a + 15) } 

p = 2 * { (8a + 120) / (a + 15) } 

p = 2 * { 8.(a + 15) / (a + 15) } 

p = 2 * 8 

p = 16 m 

The section is 50 cm, i.e. 0,5 m: 

= 16/0,5 

= 32
