Afarmer divisids 20acre sections into 1-4 acer sections into how many sections does the farmer divide her land

80 - 1/4 acre sections

Step-by-step explanation:

If the farmer is dividing her land into 1/4 acre sections...

1. there will be 4 sections in one acre (4/4 = 1)

2. multiply 4 (sections) by 20 (acres)

    4*20 = 80

Step-by-step explanation:

Side 1 = a

Side 2 = b

Side 3 = c

a = 2b

c = 5ft. + b

a + b + c = 49 feet

Substitute

2b + b + 5ft + b = 49 ft

Add the b’s

4b + 5ft = 49ft

Subtract 5ft from both sides of the equation

4b = 44ft

Divide both sides of the equation by 4 to isolate b

b = 11ft

a = b * 2 = 11 * 2 = 22ft

c = 49ft - 11ft - 22ft = 16ft

Hope this helps :)
